Pick-n-pull has a ‘85 Buick LeSabre. I’m going to check it out tomorrow. My limited research tells me it should have a 200-4R in it maybe? Is it going to be regardless of motor? I can look up pan identification graphics, but are there any tags or stampings I need to be aware of/look for?

Yes should be an ID tag at the tail end of transmission on passengers side.
Should be one of these

​​​​​​BRF 1986-1987 Grand National, Turbo T, T-typeBQ 1984-1985 Grand National, T-type
BR 1983 T-type
CZF 1985-1988 Chevrolet Monte Carlo SS
CRF 1985-1988 Monte Carlo 305 engine LG4

OZ 1983-1984 Hurst Olds
OM Oldsmobile 350 Diesel Engines
OG Oldsmobile 307 Engines
BY 252 V6 cars

These are the sought after 200 4r

That list is not complete. Here's a more complete list. The tag will have the two letters on the left and an "F" on the right.
A 1985 200-4R in a B-body with an Olds 307 is probably an OG F or a KC F tag.

1986-up use an "F" at the end. Such as mentioned the 86/87 442 KZF transmission. There will be a KZ on the right side of the rivet on the tag and an F on the left side of the rivet. It's also stamped into the tag ID number.

1985-earlier 200-4R's only use a 2-letter code, without the F. Such as, if it's an OZ, it's just OZ. Nothing more.

For the most part, the thing that really matters is the valve body. Otherwise, there's really nothing special about any of the 200-4R transmission if you're going to build for performance. The aftermarket has billet servos and rebuild parts that you can make your 200-4R close to bullet-proof. Even governor weights/springs can be played with to get the right shift points you want. And the cool part is you can play with the governor by only having to drop the pan. Just be careful with the gov cover gasket and you can keep re-using it.

Here's a tag on a 1985 442 transmission with an OZ transmission. You should find the tag in this location regardless of application.



Regardless, this is the pan you're looking for.

Just FYI, the original trans in my 85 D88, the one I pulled out myself and am rebuilding right now, has a three letter code with the F at the end.

Thanks for all the help. Of course the car was in the middle of a massive puddle. I did lean underneath and verified the pan shape.
