Okay, some bad news. Turns out most tranny shops want too much to swap the output sahft on the 4X4 4l60e. So I'm starting to rethink my options.
1) Try to trade for 2wd 4l60e.
how many miles are on your trans? do you know it works well for sure or did you buy it withtout test driving the donor vehicle? if you sell/trade, you might end up with somebody else's problems.....
i'd say pull the pan and have a look in there. if the fluid looks good and there's no debris in the pan, get the output shaft replaced.
2) Use chevy transfercase behind current 4wd 4l60e.
don't!
not only will you have to go with a gm t-case and sye kit as well as a different rear axle, but you'll end up with way more driveline angle since the domestic t-cases utilize a rear output that's inline with the transmission main shaft. that's about 7" higher than a cruiser case.
3) Full rebuild on current with upgrades TCI kit.
why? if there's nothing wrong with the trans then i'd have a shop replace the output shaft, maybe put in a kevalr band and check all the frictions. go with some kevlar frictions for od if need be and have them reseal the pump. they'll be able to determine what it needs if anything when they tear into it.
4) manual transmission options (trying not to go this route)
i like autos.......
What do you guys think?????
