Tonight while driving around the gold coast my auto gearbox wouldnt change out of 1st gear and just seemed to rev up to redline.Gearbox was fine only seemed to start playing up after leaving my house,as usual i parked my car in my driveway which is a 30 degrees incline

1 out of every 5 times it would change out of 1st into 2nd

i am now driving in snow atm due to this problem

i have a seperate transmission cooler up front but not the stock radiator one, as my radiator started to leak and had to replace with a manual radiator.

i only flushed out the tranny fluid 200kms ago and i did this as the oil was black and would change gears at 6000 revs. after changing the fluid and cleaning the tranny filter it seemed to change gears at 3000-4000 revs.

ive noticed some oil at the bottom of the radiator, could be transmission fluid leaking from the cooler, would this affect gear changes in 1st?

thinking of getting the gearbox checked out, how much would it cost roughly to get checked out?

any reccomendations on reputable transmission places on gold coast?

sorry for the long post, i just want my car to get all better lol,

p.s if anyone has any ideas on whats wrong/advice with the gearbox or if youve had ur own experience please post

thankyou guys i appreciate your help

Haha "driving in snow" on the gold coast.

If you find the box is dead I have one left over from a half cut.

your gearbox is f**ked. having only the one external cooler has probably cooked it. when you stick another auto in it or get yours rebuilt find an automatic radiator stick it in an hook up your external cooler aswell to stop this happening again

after a night the car in the garage ive checked the transission fluid to find it below low.

when i checked the fluid level last night it was above high but this could be due to the oil sloshing around up the filler tube and making a false reading.

atm im taking the radiator out so i can get to the seperate tranny oil cooler and check where its leaking from. hopefully once the leak is fixed and once topped up with oil it will work again.

as soon as this is done i will take it to get the gearbox serviced and checked out.

anyone have any good reccomendations on transmission places to get a service located on the gold coast that know skyline gearboxs well?

thanks again

after driving around for a week, it doesnt seem as bad as it is.

after i rev up and back off in 1st gear it changes now, and it only happens like once or twice when i go for a 15min drive around the gold coast.

The oil was black when i got the car and changed it immediately, hopefully the gearbox will last till i get the $ for a manual conversion.

anyone know roughly how much a manual gearbox with conversion parts costs?

does anyone have a manual gearbox for sale?

thanx again

my brother looked at my car this weekend and discovered that my r32 gts25 was originally manual not automatic.

we confirmed this after seeing a plate with bolts covering where the clutch master goes through the firewall, and looking at the auto brake pedal assembly and discovering yellow/whit paint mark on it, meaning it was bought from the wreckers

my brother also said there should be another cable going to the throttle body other then the accelerator cable. he said it was a "kickback cable" or something like that.

1)if possible can someone take a pic of their automatic auto throttle body to show me the 2nd cable or confirm me on this?

2) ive tried the gearbox diagnostics but havent got it to work any tips?

3) my brother told me i probably still have the manual ecu still in it would this prevent the auto diagnostic from working?

thanks again

p.s- do you know anything else that i could ckeck eg electrics to confirm that the auto gearbox was installed properly and that it has all the essential parts

auto skylines have the plate on the firewall blanking off the master cyln location for manual cars, as for the whirte/yellow paint or whatever this doesnt mean much as a lot of this sort of gear is marked off on the production line...

so the replacement engine in my r32 gtst rb20 must be out of an auto?? cause i have a throttle body with a place where i can put 2 cables if i need to but it only has one lol. i always wanted to know what that was for

could be, but their is a possibility that nissan made the throttle bodies the same as to save on costs of changing the design and making seperate throttle bodies for auto and manual.

So can anyone get a pic of their auto throttle body or confirm that a second cable is attached to it??

thanks

thats for cruise control...

Skyline autos are electronically controlled, gone are the days of cable operated kick downs ;)

oh true

my sisters boyfriend yesterday told me that when he had an auto car it did the same thing once he backed off it would change.he explained that the oil pickup line was clogged!!

when i changed my gearbox oil 2 months ago it had grey sludge at the bottom kind of like lard, but i didnt fully flush the gearbox properly.

anyone had the same thing???

will take my car in to a transmission specialist on the weekend

if the oil pick up line which is a filter is blocked the gearbox has worn out something and is buggered. grey sludge doesnt show any good signs either. are the transmission shops over there open on weekends are they?

Mate i don't seriously think that would be the main cause. I have only a B&M cooler(not a very big one) in my trimatic and with even a 3500 stall converter and driving to work with only second and third gears (first is stuffed) which places massive strains on the converter and oil, my temp only reaches 90degC. Though i have a auto temp gauge so i know.

I did away with the oil running through the radiator, though prob not so good down here in syd during winter.

They don't have cable kick down's anymore, like someone else said. He's prob from the ol' school holden era. The kick down is controlled via the TPS. There is 2 parts to the TPS, one for the engine, a rheostat(variable resistor), and idle and fullthrottle switches for the auto.

Mate it sounds like one or some of the solenoids are stuffed internal in the box. Worst part about these boxes.... They cost a fair bit to fix.

You probably have torched the box in the past and by the sounds of it done some pretty serious damage internal with all the black oil and sludge type stuff. It can come from many places inc the converter as there are plain type bearings in there and the lockup pads.

Mate just get another box, they are pretty cheap. Or get a fully built box.

Thanx man

got my car checked out on monday,everythings working fine electronically, we found the cause to be one of the clutch bands is wearing out.Got quoted $3000 to get fixed including parts and labour.

The owner told me the gearbox will fully wear out soon as the wearng of the band creates debri which can wear out a drum at the back of the gearbox, so atm im saving for a manual gearbox and

parts i have $650 atm.

ive located a manual gearbox for $650 anyone have a rough guide on how much the other parts for the conversion will cost??

me and my brother can do the conversion ourselves, my brothers converted an auto 180sx to manual.

p.s if the auto gearbox completely dies before i get the money for the manual conversion i will buy a second hand automatic box.

dj labby, you obviously dont drive your car hard enough to get it hot. having a pissy little transmission cooler on the front of your car for day to day driving does no good watsoever. driving around with only second an third isnt good either which also tells me you dont really care which is why you only have a not very big cooler

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
