Well before my truck had a fluid leak the tranny would shift late when it was just started from sitting overnight then once it hit just under 210 on the temp gauge it shifts fine. What happens is it revs high then goes to 2nd and revs high to 3rd then rest is fine. Also I have a leak and no money. Anybody used a transmission stop leak that seemed to work temporarily? Note lol.. im wondering if theres a stop leak fluid at Autozone that would work ok? cause i live right by one. Thanks ahead of time.

 

Have you ck the fluid level ? it maybe low, low fluid will cause shifting problems. And depend were the leak is. If it a front pump area thats leaking,a stop leak may not be the fix.
