700r4 trans from a camaro or newer truck?

[shortchevy84]

hi,i'm trying to find a 700r4 trans for my 86 chevy with a 350 crate motor from year one. i want to know if i can use a newer 700r4 as it seems to be the most readily available, and for a decent price. the guy that is selling says its from a 88-93 chev 2wd 5.7L. i'm using it in a 2wd as well. i want to have as little issues as possible. also, is the driveshaft for a 700 is a different length than one with a 350trans? also, are 700r4's from camaro's easily usable as well. thanks

All the 700R4 (4L60) trans are interchangeable.  I have one from a 90 Camaro in my 78 Jimmy.  If you currently have a TH350, the trans crossmember will need to move back and the driveshaft is shorter.  Andything from 88-93 are good with all the upgrades.

ok, good to hear. by move back, do you mean i have to drill new holes and move the crossmember back, or are they welded in, (i haven't been underneath the truck in a while.) i also have been told i need a different column to make sure i can get my 1low gear. and the cluster that shows OD as well. i guess while i'm at it, the truck is american in MPH, and i am in canada, so is it a direct swap for the entire gauge cluster to kph, or will it need to be recalibrated? is there any special linkage or anything i will need to make it work with my holley carb? sorry for all the questions, i want to be driving this truck this summer, if at all possible, as i miss driving it!

The transmission crossmember is bolted in.  And I bet the holes are already there, as my 1985 model came factory equipped with a 700R4.

82-87's should already have the holes in the frame. 73-81's won't.

ok, thats some good news! i've been reading other posts from others that have done the same thing, and have read about the vacuum switch thing, and a brake cancel switch. how hard is it to install these, and does anyone have pics? i have basically no knowledge of transmissions, as i'm an apprentice in a shop and haven't gotten that far yet. . anyway, i just want to get an idea if this is something that can be done easily, as i don't want to burn up my transmission. thanks again

ShortChevy, The answers to a couple of your questions...I have no problems with the '85 original steering column going to low (mine was a TH350). You will need a couple brackets for your Holley to work correctly. A TV cable bracket & a corrector link (for the cable end to hook to), this makes the distance of the pull correct as the throttle is opened. Lorne

Sonnax makes the TV geometry corrector you need.  This is what HAULIN IT was refering to.
