I have an 80 TR8 (5 speed LT77).
Starting a few months ago, I sometimes have problems getting into 3rd gear. It only happens when I go from 2nd to 3rd, and never from 4th down to 3rd. It might be a little worse when cold, but can still be a problem after it has warmed up. I would guess this is an issues around 10% - 20% of the time I go up into 3rd.
It does not grind, or make any noise. The stick shift simple will not go to where 3rd should be. If I cannot “find†3rd, I can put it in 4th or 5th without even releasing the clutch, I can then put it in 3rd with no problems.
I use Pennzoil synchromesh fluid, and I have changed the fluid since this started happening. There was a little swarf on the drain plug when I changed the fluid, but I wouldn’t call it excessive.
My first guess would be a synchro, but I am not a tranny expert.
Do I have a transmission rebuild in my future, or could this be something simple?
