4L60 Rebuild????

[naphidim]

This will be my first time ever rebuilding a transmission, I have a 1990 Chevy v6 4.3l TBI engine with a muncie/getrag 290 5speed w/overdrive tranny in it. Going to be swapping out for a 4L60 Tranny. Decided I would try to find one at a junkyard and just rebuild it? My question- Is the 4L60 tranny one of the easier rebuilds, i have the rebuild manual for it, so figured just take it one step at a time and i should be ok. Am i in way over my head since i am kind of a beginner mechanic.......should i just by a rebuilt one, new one, or should I rebuild one?

Build it yourself... you will be proud everytime it shifts! Make sure its a later model 30 spline 700R4. The easiest way to make the lockup kit is the relay kit. Any questions just post them or welcome to mssg.

Thanx, u got any ideas of mods i could do since i'm gonna be in there anyway, i want to try to keep it as friendly MPG as possible but also would like to be able to go around someone slow on the road quickly if i had to, get my drift, i know i pretty much have to sacrifice and try to meet somewhere in the middle with it but any ideas would be greatly appreciated, thanx again

and these mods won't drain too much MPG?

They won't affect it at all.

also one last thing, i have a manual transmission right now ok, so is the 4L60 tranny also equipped with a floor shift or is it a column shifter? could of sworn it was a floor shifter but now not so sure....

If you put a shift kit/ shift improver you do not need a corvette servo... All the Corvette servo does is firms the 1-2 shift and the shift kit will do that.

The vette servo applies more pressure to the 2/4 band... It helps more in holding power against more torque. That is the main advantage. A crispier shift is a bonus. It is most defiantly needed as the band is a week link in a 700R4. We don't build a 700R4 without at least a vette servo.

which one is cheaper and easier, and again the 4L60 tranny is a floor mount shifter right or not?
