how bad does it slip. my th350 needs to be rebuilt but i put in anti-slip trans fluid and it made a huge difference. you can try that but if it is real bad i am not sure what to do.
try some Lucas Trans Additive! IT worked for me !
Make sure..
Check the modulator valve,and make sure it has good vacuum at its hose when engine is running--a bad modulator valve will have tranny fluid on the hose connection side if its diaphram is ruptured...and that will reduce the line pressure to the clutches,and let them slip...also a partially blocked filter can cause silppage too,or one that has a missing or broken gasket can too..but there is always the possibility something was not done right during the rebuild also...hope not..
