I have a 92 Z with the automatic. I always thought that it was a 700r4 but did I read that 92's came with the 4l60? Any help would be great since I keep destroying the 700's

 

same thing different name...

If your tranny is in good shape...simply a shift kit and a corvette servo should be enough to keep her going. I'd recommend the transgo kit, it also comes with a servo. TV adjustment is crucial.

Also depends on how many ponies you're pushing, seeing your sig says you have a 383.

My buddies and I dropped my 350HO in my 87 about 2 years ago. It was originally a 305/700r4 deal.

I would say I'm pushing a lil over 300HP, and my tranny is just now on its last leg....I think the 3/4 clutchpack is toast.

...All in all, a 4l60 is a 700, and a properly running 89+ tranny w/ mild upgrades and a correct TV should be enough to keep you on the road, depending on how wild that 383 of yours is...

 

as far as i kno the 4L60 and the 700R4 are the same trannies. the main difference that im aware of is that the 4L60 is an electronicly controlled tranny, controlled by a PCM, where as a 700 is not. good tranny for mild power tho. hope that helps.

I knew that the 4l60 was electronic and the 700 wasn't and I thought that the 4l60 started in f-bodies in 93. I would kinda think that if you interchange them that the way they shift would be impaired. I was just curious what was supposed to be in the car

 

The 4L60 is the same as the 700 except the 4L60 used a electronic speedo sender instead of a cable driven one. They both used TV cables. The 4L60E started in the 4th gens and was fully electronic with no tv cable used.

 

the 4L60 started in 94 cause the 93 cars were still ecm controlled. atleast i think thats right

 

A 4L60 and a 700R4 are the same tranny. A 4L60E is an electronically controlled version of the same tranny and was introduced around '93 (back from my S-series days, I'd imagine it was the same for the f-bodies).

 

Just as a little exta info. The 700r4's and the 4l60e's use different filters in the pan. Found that one out myself. As far back at '88 some of the F-bodies had electrically driven speedometers. I've got an 88 Formula and a 91 RS with wires instead of cables. Oh, the RS is a 5 speed but the point if electrical speed sensors were used prior to OBD2 cars

 

4L60= non ECM cntrolled 700r4

4L60E= ECm control 700r4

E is the ECM control,

its real simple

4l60E came around in different years for different vehicles, as early as 92 and maybe some 91's

it was a phase in over a few years, hit and miss
