Hey guys, i havent been on here in ages! been busy and what not, so here it goes.

cars been extremely good behaved for the last year or so. Servicing it on time, everything .

Untill last night.

Was driving fine, until it felt like the auto was being a C**t first and second arent too bad. Thirds ok, 4th is not holding. i dont know how to explain it.

is this telling me the Auto is Rooted and its time for a manual conversion? or am i going bananas and need to fully flush the auto . I did service it not long ago

Any help would be great.

Btw : In overdrive it drives somewhat ok.

im kind of nervous and worried.


A very unsettled willzgtst.

Cars not running any mods. apart from pod filter.

could be any of a lot of things wrong with it. .(even the convertor) very good idea on the flush but before you do that id be checking the filter screen after you drop off the pan, depending on what / how much crud you find on the screen will be the deciding factor as to wether its f*kd or not

Can you be more specific with the symptoms?

"4th is not holding" - does that mean it feels like the internal clutches are slipping/flaring, or is the shifting going haywire eg going up and down in gear and power constantly dropping off.

Check the throttle position sensor. If it goes faulty the shifting goes haywire.

Ok basically up to third is ok , once in fourth as soon as I push the accelerator down it kicks back but it feels like it's slipping if I let go of the accelerator slight it drops the revs , I have been driving in overdrive as that's the only way it's drivable ATM .

probably the best idea is to replace it with a good secondhand unit with warranty, they are going pretty cheap.(rebuilds are over $2000) . . while things are apart i suggest you get a tranmission cooler fitted

all running smooth and fine. dump pipe was put in so thats a bonus also. u can really tell the difference between healthy autos and unhealthy , this gearbox changes gears where it should. The other one would wait for me the lever the accelerator and if i didnt, it would slip and take its time.

Thanks for all the support fellas! :action-smiley-069:

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
