My problem:

my jdm itr transmission went afoul at the track a couple of weeks ago. it would not shift into 4th gear. there was no grinding....nothing, like a brick wall! two passes and it did the same thing both times. on the third pass it went to second. it jolted and i got out of it instantly. when i got back to the pits i was reversing into my spot and reverse was all spongy. it also was hard to get out of reverse. i limped it back home (also toasted the inner joint on the drivers side axle in the burnout box on the last run....damn aftermarket axles!) also noticed it will sometimes grind going into fifth gear. under normal driving conditions it seems good. never had a 3rd gear grind.

Now:
-Anybody have any ideas before i tear it down?

-I am a tech at a Honda dealership, what manual can i use for the inspection? itr,gsr,99-00 civic si?

-Are all b-series transmission clearances the same? Just different gears?

I am open to any advise or theories from people who know what they are talking about.

My hypothesis is a bent mainshaft shift fork but.....who knows

thanks, Mike

 

can you get into gears with the car off?

 

car drives fine normally. its not the clutch

 

Mainshaft bearings or shift fork(s) is my guess.

 

thanks, anybody got any idea about which manual to use?

 

ITR will be the closest.
