If i had clutch -pressure plate- T-Out bearing problems it would do it all the time?I have access to a replacement trans so i may just change it. I know it is best to get in there and look at the guts but it may be easier to just swap to the new old one. This is only 1st when you start out from a stop sign.

Pop open the inspection plate and see if the gear is worn or has excessive play, or teeth at the bottom. Let us know what you find. | | | | | Joined: Sep 2012 Posts: 112 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2012 Posts: 112 | Time to jack her up and crawl under this weekend.

It is common for the first gear side of that gear to wear through the case hardening much faster then the reverse side as it does not see as much use.
