Default 4l80e vs 4x4 4wd 4l80e. whats the difference?

I found a cheap 4x4 4l80e to replace my trashed one. I am not sure this can be a direct swap though. I'm hoping I could just take the old output shaft and tail shaft off of my old 2wd unit and put it on the new 4wd unit.Is this possible? Vince?

THe output shaft and rear case extension are different. Not sure of anything else. If none of that is trashed in the 80e you currently have perhaps they can be swapped over to the 4WD tranny you buy. I am pretty sure that is it... but ya, Vince would know for sure

when you say"rear case extension" is that another word for tail housing?

All you do is change the output shaft and install a 2wd extension housing nothing fancy. The case is the same 2wd or 4wd regardless of year model.

the old one is an 03, the new one is said to be an 06 but it has a 07 on the tag so it should be an 07

ok I would be intrested in the 4x4 output shaft and possibly the adapter if it's still attached to the case when you get it.

btw whats wrong with the 03???

Well for starters, the bell housing broke when I blew the drive shaft 15 minutes after I did the 4l80e conversion, which I found out when I was dropping the trans. 4 of the seven bolts held pieces of the bell housing to the engine when the transmission free'd up from the engine. Secondly, the clutches burned because I didn't utilize the longer 4l80e rear cooler line fitting in the rear of the case. So obviously I can't rebuild this unit. I can only salvage hard parts and the shift kit. So-Cal, where are you located?

You do need to make sure that both output shafts use the same style lube systems. The later 97^ shafts do not have a lube hole in them while the earlier shafts do have a lube hole in them. Also when converting from a 4x4 to a 2wd you will need to install a lube orifice in the back of the case for the extension housing bushing. If you do not do this you will smoke the extension housing bushing and also a yoke. HTH Vince
