RB20 Auto Transmission

Postby A31 Cefiro » November 16th, 2007, 6:39 pm

My transmission seems to be working fine sometimes, but other times, the gears dont change like they're supposed to.
I'm thinking that the transmission is moving off its alignment to the engine.

Is this possible?

If so... does anyone know where I can take it to have the necessary adjustments made?

On rare ocassions I can actually kick down,
Other than that... I can floor the pedal and the car just moves along lazily

Any advice?

I wont mind fixing the problem myself.... If someone can tell me what to do

There is a small sensor on the transmission itself ....I believe that the sensor trips and sends a message to the brain and so the car feels sluggish. I cud be wrong

I have a spare parts for the rb20 and 25 transmissions....325 0015

I fixed it today actually! :)
I removed the panel that fits around the gear lever, and I noticed that the metal plate, that the gear lever sits on wasn't secured properly.
So I tightened the screws, and went thru a long process of testing and re-adjusting... until I got it right.

It works fine now. :D

I got my RB monster back! :onfire:

Ok... now its working on and off
It works fine for a while and then it goes back to how it was.
I have to cut off the engine and restart for it to work again.

Also... when I start the car first thing in the morning and put the lever in D, It feels like its in neutral (just revs) :(

Nice to see you've got your baby up and running A31 Cefiro. You've made a lot of threads lately about bringing it back. Hope it all works out for you. Who knows we could meet sometime and discuss ideas on our cars. 0X

Hey A31 is the tranny DE or turbo? i had that same prob with my tranny so i got the turbo and everything worked out fine.

Hey Conrad the set up of the R33 should be the same for the ceffy and also the coilovers should work bolt for bolt because i believe its the same model or close to chassis

hmmm last time i checked about $2000-$2500, doh worry man it worth it in the end! Totally different drive, the response feels a lot more powerful and it could take jammin, it may cost big bucks but worth it trust me.
Us A31 Cefiro guys need to stick together. 0X

did u reset the ecu
since the engine was running like that, it may have thrown some adjustment into the mix and may still be reading like there is a problem
