Are you getting codes from the TCM? If so, need them to help diagnose your problem. What converter did you put in?

[04dirtymax]

its a daaco convertor i thought that would fix the problem after i put it in but it still does the same thing. who can diagnose that problem?

Where are you getting your advice?

[04dirtymax]

what advise?

[ob_1jr]

sounds like you need to upgrade the clutches too. Your question is vague at best though. What codes you have?

correct. slippage in the clutches leads to the characteristic limp. Put it in neutral right away and it may clear itself.
