Hi Guys....

I performed the shifter TSB DIY a few months and couple 100 miles ago, as I had lost my reverse lock out. Used all new parts, plastic bushing etc, everything recommended in the the FAQ. Was beyond pleased with the results, a smoother shifter and more importantly I had regained my reverse lockout. Now, a few months later, I find the car to be fine until the transmission warms up after a half hour of driving. I will lose my reverse lock-out. The next cold drive I will have my reverse lock-out. A half hour later I lose my reverse lock out. Found some threads from many years ago about this happening with no real fix. I thoroughly cleaned and installed everything right. Did my transmission oil last year. Barely drive the car. Guess I will just redo the TSB. Is there any updated knowledge on this? I'm amazed heat can cause a simple spring function not to work. Think I need to re-order parts again?

Thank you for your knowledge,

Greg

 

Is it the case that you cannot select reverse or that the spring resistance is lost?
In any event I am thinking this is not a shifter issue but rather clutch line or transmission

 

Thanks for your reply, but I am able to engage reverse using the reverse lock out when the car is cold. After 30mins of driving, I can still engage reverse just fine, I just don't need to use the reverse lock out. It's like the spring that props up the shifter disappears when the transmission is warm...

Thank you.

 

remove your shifter assembly and regrease it. Double check the spring. There's no other way
