SIKHS 5

i finally got my driveshaft and slip joint off today, my older transmission was a 700R4 and the one i switched to is a 4L80E

I know i need a TH400 (or 4l80E) end for the trans. but i have no idea how to identify what "type" is needed to fit the driveshaft (and also what kind of u-joints i will need)

any help would be greatly appriciated

here are some pictures:

I like the Neapco book to measure them up.

My guess would be S44 on the driveshaft and a 1350 on the TH400 yoke

it ended up being a 1310 u-joint size in case anyone was wondering

picked up two new u joints and ordered a 1310/th400 slip yoke

taking in the driveshaft to get the 2 old u-joints pressed out, 2 new joints and the slip yoke pressed on --- the guy said he will charge me around $60(he said he usually charges $80), does that sound reasonable?

$30 each end sounds very fair. Heck I have a press and wouldn't do it for that little! Even with a press it's not always fun or easy getting old, rusty, frozen cups out.

If he can spin balance it that's worth doing too unless you know it ran smooth at speed.

i had a feeling it was a decent price(wrestled around trying to take off the slip yoke so i could measure/order a new one... wasnt fun not having a press lol). the guy owns a little auto shop down a couple buildings from my dad's hardware store, nice guy overall.

i had the driveshaft in with my tbi350/700r4 and i never had any problems with it(has some weights tack welded it to - not sure if that was from the factory or the previous owner). im going to prep it a little and spray it down with some rustoleum "black hammered coat" to clean up the surface rust on it.
