Triumph TR6 - Difficult to shift when engine is warm

This is a new one for me, but then they all are! The other day I was giving rides to the kids and after driving 1-2 miles, shifting became nearly impossible to shift gears. Same thing a couple days later. It shifts like butter for the first few miles. What could this have to do with temperature?? When the ignition is off, shifts fine.

BTW, which one of you guys was driving your green TR in Benzie County Michigan last week? I saw you!

Are your clutch hydraulics recently rebuilt? I think it's your clutch that's not releasing fully (adjustment, bleeding, maybe more, but try these first).

What you are experiencing is very likely the release bearing carrier binding on its cover. When cool, there is plenty of clearance; heated, the clearance disappears. The solution is to hone the cover and chamfer the edges, all described at Buckeye Triumphs (read also the Gunst setup while there).

Another possibilty could be your thrust washers. The oil heats up and thins out allowing play if they are worn. Warm up your engine then shut off and push back your damper pulley with a bar or something toward the rear of the car. Have someone engage the clutch while you watch the pulley. If there is quite evident movement; they are worn. Lots of info in the archives and other site about properly measuring and changing them. Not a huge task.

FYI...the solution was new clutch slave cylinder and 2 clevis pins, replaced pedal bushings too

Hmmm, glad you found the solution. I'm still puzzled how that was heat-related.

If the problem is related to heat you probably still have a problem. Something similar happened to me. In trying to find my problem I replaced clevis pins, welded and redrilled the hole in the pedal assembly, and so on, which were all well worn. I could shift again; however not for long. Other parts were worn especially the thrust washers. A couple of months later my shifting problems were back as the thrust washers continued to wear. I hope you have found your problem and it's that simple. However I would still check the play on those washers just in case.
I know a some of the guys on this site have said that a low clutch is normal on a TR6, I have to disagree. They didn't come from the factory with a clutch that engage a 1/2" from the floor. After struggling with a low clutch for a couple of years, I finally changed or repaired every possible component that can wear. My clutch is as high as any other car. It really makes it a pleasure to shift and I never have problems going into reverse ever!
