TH350 to 4L60E???

[BADAZ chevy guy]

How big a deal is it to swap a 4L60E Transmission in to my 77?
I just found this on-line for $200.00 >>> http://www.ksl.com/index.php?nid=218...arch=&ad_cid=2

well for starters your gonna need one that has manual shift linkage, a stand alone TCM, shorter drive shaft, you can grab one of those out of a TH700R4 truck. i wanna say that the rear mount is different but i could be wrong. you also will no longer need a vacuum line running to your transmission for the shift modulator after the 4L60E is in. i maybe leaving out more specifics im just going off what i know the main differences are in TH350 and 4L60E transmissions. there is possibly more little things that you may have to do. ive personally never done if but i know people that have.

I'd stay away from that transmission, not worth the time to do the swap. if you really want the benifit of extra gear do a 4l80. ive blown up 4 4l65s behind my iron block ls1 in my 01 pickup and its a never ending problem. just not ment to be driven hard. thats my opinion

4L60 Transmission build

Hey guys, I'm back. So, I have a 4L60 ready to be rebuilt. I have all the parts (Mostly Borg Waner) a Sonax sun shell, new bearings, sprags, bushings and a stand to do all the work on. Here's the before photos and I'll have more as the build continues.
Wish me luck!!!
