Car:1980 Triumph TR7 5 speed manual hydraulic clutch ...MY CAR WAS NOT LISTED on 1990 Jaguar XJS

After the car runs until its hot the gears grind sometimes and are harder to shift especially 1st and Reverse

Asked by for the 1990 Jaguar XJS
sounds like a pressure plate failure in the clutch.

which car do you have??

Roy...I have a 1980 Triumph TR7 30th Anniv. Edition Roadster which I bought new, 4cyl, 2ltr, 5speed trans
Thanks for thr feedback, I think it's clutch replacement time!!!
Regards, Jack Russell

Last fluid service? clutch master cyl. leaking/air in it?
NO....It's checked every 2 weeks...I think the pressure plate is the problem, I'm going to replace the clutch...It's 10 years old, and overdue.
