TR6 Transmission keeps getting stuck.

I can drive around for a little bit and the trans is okay, but once the car heats up the trans starts sticking in gear and I can’t move it without feeling like something’s going to break, and it grinds when I try to put it in reverse. But then the most confusing part is sometimes it just goes right back to working perfectly fine, no sticking no nothing.

I’m wondering if there’s something in the trans or maybe the clutch is having problems.

I’m really confused and would love to hear if someone else has had similar problems.
 
Topped it off with what? I tried the 30 weight non-detergent oil that some owners run and quickly switched back to the redline gear oil for o/d gear boxes and my (short lived) shifting problems went away. That was over 10 years ago and it has been fine since…

:iagree:
 
Your description is a clutch problem, not tranny. It is not releasing fully, although the question is why it is intermittent. Check to make sure there is not carpet or mats fouling the pedal. Then bleed your clutch system. If that still doesn't fix it, then look closely for worn linkages and make an adjustment by the book.

I topped it off with the same stuff I’ve used in it for a while.

John I am having the same issue with the TR6 trans in my TR3 specially after a hard run when I try to get into reverse! If I need to make an adjustment do I need to check the distance between the "MC clutch rod to the stop bolt" or should I not even have a stop bolt there at all? As for the slave cylinder adjustment.......I find that I tend to break the stock return spring when I try to install it. I substituted a large generic spring the last time it broke and it is still there. Would too much force from that spring be causing the problem? Do I disconnect the return spring when adjusting the slave rod? Karl
