not sure about the transfer case but as far as i know you can use any year 4l80e for the swap.Quote:

Just need that input gear for the tcase that accepts the 80e output shaft.
You can use older 80e's as well, mine Is out of a 93 Rv
Would it be cheeper to use the transfercase from a 2500 with a 80e? or will it even work?
ya thats what im wondering. i want to find the best deal on a trans and transfer i can to get my truck on the road.i found some from a 98 but its the older body style so i wanna make sure befor i buy it.
24x or 58x?
whats that mean??
i think he wants to know if you have a gen3 or gen4 engine. What color is the crank sensor, up next to the starter on the side of the block? Black is gen3 and white or grey is gen4.
yes thats what i wanted to knowQuote:

likely has iron cylinder heads, right? Any 99 and earlier 80e will bolt right to it if it has the stock flat flex plate on the engine. If you don't have a flexplate on the engine, look at the crankshaft at the back end of it and if the crank sticks out of the seal about 3/8" you just need the flat flex plate and old style 80e torque convertor.
yup it does.. i got some 243s to put onto it luckly :) so pretty much any year 4l80e works then. i know the crank sticks out for sure. thats one of my problems. and i have a flat flex plate. the only difference is the torque converter between the older 80es and new 80es??
