hey guys my gf got a 34 with tiptronic auto. just wondering if anyone has had a shift kit put in thiers?? if so who did it, how much was it n did u get much improvement from it in fuel economy or performance n is it worth doing. just askin coz the stock auto feels a bit sloppy. in the mean time im gonna get the oil flushed n see if its any better.

I got what you might call maybe a "Stage 1" shift kit in my wagon (same gearbox but with a transfer case on the back).

Basically I took it to this guy in Bibra Lake who talked it up and then it turned out he hadn't seen one of these boxes before. So not knowing what galleries did what (there's more solenoids and valves than a 33 box) he did what he could, which was remove the accumulator plungers on the 1-2 and 2-3 shifts, and replaced them with welsh plugs.

It's made a huge difference, mostly on the 1-2 shift, I used to have to shift either early or bounce it off the limiter otherwise it would just slip (incidentally, even with all the slippage, he said the inside of the box was squeaky clean).

He didn't charge me much as we didn't achieve what we set out to achieve but to be honest, I'm not sure I would want any firmer shifts in my daily.. the place is called Global Automatics in Bibra Lake.

so it doesnt slip as much anymore while its in gear? n how harsh r the changes? like wheel chirping when it changes? did it improve fuel economy? also does the gear changing rpm change or is that to do with the computer?

It never slipped while in gear, there was just a massive flare from 1st to 2nd if the engine was making heaps of torque.. i.e. if it was on boost over 4000rpm it wouldn't want to go in to gear unless I backed off the gas or let it bounce the limiter once. Now it just gets the fuck in there!

Shifting is more positive and it would probably chirp 2nd if I didn't have 4WD. Put it in 2WD and it's highly amusing in the wet, as soon as it comes on boost, click 2nd and it shifts instantly then it's lunchbox super happy fun sideways time.

The 1-2 shift is harsher at slow speeds and I had to relearn how to drive.. I used to lift the gas on the 1-2 shift but if I do that now I nearly hit the car in front as it lurches hard.

It's not as full on harsh as say an MV Auto shift kit where the valvebody galleries are modified, but it's a very positive shift, no fucking around.

I would say it has improved economy somewhat but more importantly, it improved drivability tremendously!

Oh and when in tiptronic, the downshift to 2nd is INSTANT.

Edit: shifts may be nicer if you have stock ECU.. I have a Haltech that doesn't talk to the TCM so the ECU doesn't cut ignition when it comes time to shift, I also think that is why mine had so much trouble trying to shift into 2nd.

i just recently put shift kit in my 34 4 door. purchased the valve-body kit and the shift solenoid from M.V Automatics.

got it installed at Wangara Auto's.

its like driving a different car. gear changes are instant. 1st - 2nd can be a bit harsh but you learn how to drive it nicely.

the car will light up the rears going from 1st - 2nd now... :-) (of course this is on the track)

i went down this path as i drive a lot and like the ability to drive it like a manual or like an auto.

although i have no experience with auto skylines, a few years back when i had a auto commodore i had the box rebuilt with a street/strip shift kit + histall and it was definitely worthwhile doing!

it'll snap through the gears instead of sloppy lurching on shifts, way more satisfying to drive

if you can find a place that'll modify your torque convertor or go a proper histall it'd definitely be benefitial as far as getting it on boost from a standstill, i had a centrifugal blower on my commo which wouldn't start really moving til 3k but once i got the histall it'd just smoke the tyres off the line

All fast torque converters do a "more stall" which is basically a standard converter with the internals tweaked a tiny bit if a high stall isnt wanted. I've installed an MV shift kitted valve body into a 34 4 door and it was a pretty good piece of gear. To get it done by someone in perth give Allfast a ring as the guy that runs it also have a transmission shop down the road and he's quite good at what he does.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
