I just pulled the tranny from my '87 GN today getting ready for a rebuild, and much to my horror I'm nearly certain it's not a BR valve body. My first tip was it only had a single switch on the top(bottom) side of the VB and only 3 wires.

Now, the case is right, it has BRF on the tag, the VB has a white marking on the side but it's almost illegable, it might say "BG" or "86" or any combo of those two, looks like there might've been 3 or 4 letters total. It also has 4203@D-10 on the VB, and looks like the 1-2TV has #13, 2-3TV #17, and 3-4TV was G.

The governor also looks like the standard, not the GN...

I guess I'm screwed huh? No wonder the thing burnt itself out. I bought this car in Nov or Dec of last year and the owner had just had the thing rebuilt in Aug, I'm guessing those crooks switched the VB on him. If I'm not mistakin he said the tranny prob was the only trouble he had since he got it at 40k 2nd owner. Makes me want to go find them and throttle them. :mad:
 
VB

Anyone??

Am I correct in my assumptions? Is this VB worth the metal it's made out of? :)
 
VB

Actually, I just went and looked at it real good again. I think it might be an O, O6 or OG more likely.

I was wondering another thing, is there any markings or p/n on the servo or piston that would tell me that's a GN servo?
 
Servo

Well, looks like someone stole the damn servo too. It's marked with 569/564piston. This really burns my ass. There is NO way this is a shop 'mistake' they got the three important components. Theft is the only thing I can imagine, they'd better be glad it wasn't my car when it was rebuilt.
 
OG is olds 307

And DEFINITLY NOT what you desire. Yes, you got snookered...

Thanks for the confermation, I was getting pretty sure of my guesses. What worries me now... I was remarking on how the pump body looked as if it were new, they prob stuck a 7-vane pump in the bastard too.

I'm considering pulling the BRF from my camaro and doing a light o/h and checking the endplay etc, hardened stator & ring kit, l/r roller if nessisary and put that back in the GN. I KNOW that has a BR3 valvebody. Then just building this core with another VB, beef it up more than I was going to for the GN and put it back in the z28.

I might have a line on a CZ, would that be plenty good enough to build for my Camaro, or should I just go ahead and buy new?

Bruce, I'll probably try and give you a ring about exactly what I need to put in it however I go.
 
Honestly...

Build the CZ for the GN. All you will need to do is lock up switches, and connector, and govenor gear. It will work PERFECTLY! Seperator plate and all, in fact, you may like the earlier kickdown more, if you have any kind of turbo on it.
Leave the Camaro alone! Don't screw with a good thing. Build the CZ and do the cheap mods that are needed and it will perform flawlessly. Would I steer you wrong? :p

Well, I just cracked the pump, it's a 7-vane. I thought it looked too new to be original, didn't the BRF come with a 10-vane pump?

What about the monty ss, it should have the cz VB, but what about the pump and servo? I might have found a 87 monte ss core.
 
well...

Ok number 1 question: No, None except 88 and later in caddys and TTa's came with a 10 vane pump. brf or cz.

Number 2: Pump doesn't matter and I would suggest a billet servo and anchor and band so that means nothing too. VB and Govenor will match and work fine. A CZ core is valuable (to me at least)

Pulled the BRF out of the Z28...

Two reasons, I need a working tranny in the buick very soon, as in this week. 2nd, I don't know if I have the money to do the other one right all in time, I would rather build it a little tougher for the Camaro with the 86 BR valvebody and servo coming..

I'm just planning a light o/h of the working brf, the required hardened parts and these B/W clutches, check the endplay etc. And go with the pts billet servo/alto band/anchor, master rebuild, prob direct drum hot loaded with the red, and thinking about at pts pump since this is the 082 7-vane....basically all the goodies that don't cost TOO much. :) Plus I have plenty of time to build it as it's not my daily driver anymore...the GN is.

Well, it's a dang good thing I did pull this one, because the stator is definately not the hard piece, I'd say the splines are at LEAST 50% worn down. It does have the 690 pump and 692 servo in it still. My question is this, other than making sure the pump has hardened rings/stator support, should I upgrade to 10-vane? From what I've read, it seems that's something I shouldn't try to do with limited tools. What about the rings, no machining required for that I assume.
