I Need help!!!

[Tommyk]

I have a 1993 ford ranger with a 4.0 and auto trans I just swapped the trans cuz I lost first gear. After the swap the truck holds idle and can redline but once I put a load on it (drive ect) after 1500 rpm the truck starts to die to keep it going I pump the gas but after it catches up stalls again now I have replaced the crank sensor and seafoamed it does anyone have any ideal why it still stalls

Just a wild guess, but maybe you didn't put everything back just right. It wasn't doing this before you lost 1st gear was it?

have you checked fuel pressure?

I would replace your fuel filter if you havent done it in awhile

Try cleaning the IAC first. Check the catalytic converter for clogging. And make sure you didn't leave a vacuum line off. This is assuming the transmission you installed isn't screwing up.
