Welcome to Hotrodders.com

I edited the thread title. We dont use ''help'' as a thread title here.

Use of a proper thread title helps the members and the search function on the board

What is the mileage on the trans (If you know) , or is this a recent rebuild?


Please clarify.. Does the trans 'not shift to 3rd' or does the engine rev up when 3rd gear should be there? The 1-2 shift is OK? Then 3rd gear is nothing, like a neutral?

BTW; 4th gear is over drive. Perhaps you are calling converter clutch lockup as over-drive?

Sounds like the 3-4 clutch pack is burned up.
