my setup is in my sig. the trans shifts great but under wot it wont shift from 1st to 2nd gear unless i let off the gas a little.do i not have enough line pressure? or maybe something i need to tune?

 

Is this in your Chevelle with 94 running gear? If it is, you should try and tune the trans shift points for your wot. Put your shift points approx. 100rpm under your peak rpm. This way you're not overreving the engine. Hope this helps.

 

ok i will try that. it has the same gearing as the donor car had.
