I had just replaced my axels with Honda OEM ones, used some sea-foam for the tranny used as per companies instructions, and filled the tranny up with Castrol GTX 10w30. I was going up a grade about 30 mph and start to slow, downshifted and almost felt like a mis-shift. As I made my way from 3rd to second my shifter felt like it got caught in neutral.

After this I was stumped, tried every gear. Also, there was no metalic noise as I changed gear as if something snapped or broke. I know there is fluid, I drained it, perfectly full, still clean. But now upon inspection only 1/2/4 are the only gears I can change into. Yet nothing engages, I'm guessing the shift fork is toasted?

Anyone have any info on how to tell, or maybe a better diagram on my tranny than the helms'. 91 CRX Si 89 Si transmission. TIA for any replies. - Darrell

 

i had a similar problem... i was just driving normal and shifted to second and it jsut stayed there... then if i got the shifter out of second, my tranny stayed in second... i broke my shift fork... it didn't matter where my shifter was, i was in second forever...

 

And did you replace the fork and life continued? Or did you get a new tranny? Or are you still trapped in second? lol - Darrell

 

at first i didn't know what was wrong... assumed it was the shift fork... i split the case and changed the fork and took out all hte metal in there... and i was good to go hopefully yours will be taht easy...

 

Ummm... 10w30 TRANNY oil...?

 

Yeah, just to verify I searched the Castrol site, and GTX is only available in MOTOR oil grades. Manual transmissions use a much thicker oil, usually something in the range of 75w90.

Sounds like you put motor oil in your tranny. ****.

 

yeah, your rite about that oil... i used mobil the heaviest one.. can't rmember hte number.. red cap? adn i'm pretty sure that the shift forks in our trannys are aluminum....

Yeah, I've done this to more than 12 manual transmissions, never had any problem with any, aside from this one. All grinded before the GTX/Lucas stabillizer combo, all were fine after. So it cannot be that bad.

Yeah, I can only hope. The tranny is 85% percent out, once its out I'll crack it open and pray for the best. thx for the replies. - Darrell
