Re: 700r4 Identification
91 Camaro or Firebird, 3.1L, Built on 214th day, second shift. FBM is the model number, which you can use to identify service parts in the catalog. Not much else to tell.

Re: 700r4 Identification
Cool thanks buddy. I'm gonna buy it off some dude for 80 bones. Most likely It is not in working order that's why it was removed but you never know. I wanna tear into it, see whats going on in there and possibly rebuild myself. I want it to replace my 92 v6 700r4 when it goes. That way I have two trans.
Re: 700r4 Identification
It is a 1991 (first digit is a 1) and for $80.00 that is a very good price as long as the oil is not black. 1987 - 1993 700R4 cores are going for $200.00 most everywhere now.

Re: 700r4 Identification
Yeah dude wanted 150 for it but I talked him down 80. Told him most likely it was no good that's why they removed it. I'm picking it up friday after work.Hopefully he doesn't flake.
Re: 700r4 Identification


Guess I shouldn't have scrapped mine then. Oops.

Where do I go to redeem a V8 700R4 case? LOL I was going to recycle it with the rest of the aluminum scrap, but if it's actually worth something.....

Re: 700r4 Identification
I know, right? I beat mine with a sledge so I could get the steel out of it to recycle it all Trending Topics

Re: 700r4 Identification
I hate when I throw stuff away and then later end up needing it.
Re: 700r4 Identification
My mistake. If it is a non V-8 bellhousing, then it not worth as much. The majority of the gear train is still useable. A lot of these have the 5,500 rpm or 6,000 rpm matching valve body and governor setup, depending on what motor was in front of it and the horsepower (at what rpm was the horsepower rated at?) of the motor. Haven't seen one of these in years.

9 = 1989 build year
yzm = trans model
159 = built on the 159th day of 1989
h = built on 2nd shift
2kl261652 is the partial vin # that the trans was installed in.
2 = pontiac
k = model year 1989
l = plant of manufacture (Van Nuys CA)
261652 = last 6 digits of vehicle vin #
