First time using the Forum today although I confess to being an avid follower and have benefitted from some great advice and tips.
I have a Type A Overdrive in my 1970 TR6 which engages straightaway when switched on however it has recently begun to disengage under acceleration?
Almost like having a kick-down in an auto transmission vehicle!
It quickly re-engages when the throttle is backed off and will cruise happily until an incline is encountered or any additional power is applied.
Oil level was fine when last checked prior to being put away for the winter, although that was a little while ago, the car hasn’t been out much (once this year!)
Suggestions greatly appreciated…
