in the middle of a transmission service but old filter doesn't match new one. I got a Duralast TF300 from Autozone. It's a different shape, it has the uplift tube more centered on it rather than biased to one end. Anybody run into this? Did they change the design? Didn't want to try fitting it in case I need to return it.
I believe I've seen the 4L60/700R4 filter used on the 200-4R but never the other way around. I believe it's used because of the "pick-up". Just return it OR did you just go ahead and use it? It's difficult to determine from your posts if it's installed or not.
Maybe someone wanted the 700R4 for his 200-4R bought both and returned the 4L60/700R4 box and gasket with the 200-4R filter. People do stupid things to swindle the sellers.

No, I pulled a 200-4R filter out of my 87. I have a 700-R4 ready to go but was a bit confused by what I pulled out. These are photos of what I pulled out this afternoon

just purchased a GM/Delco 82-93 700R4 transmission filter service kit (P/N 8657926) through amazon.
I've bought several different kits over the years, and there's nothing like OE parts. for as often as you service the transmission, IMO, i'd go first class with this one. BTW, the ACD filter is made in the USA!
Well, new filter fit fine, just need to clean up the pan, reassemble and fill. Looks like I got about 4 qts of old fluid out does that sound right?
Your post#12 helped considerably. I thought that you had received the 200-4R maybe in the 4L60/700R4 box and wanted to question packaging.
*** I did some reading regarding your issue and I believe that until the AUX valve body was added the 200-4R and the 700R4 actually used a very similar filter.
Between '84 and '88 there were 4 different part#'s for the filter from GM. '84 (1), '85 & '86 (1 and different), '87 (1 and different from others) then the '88 which is what we're most familiar with.
Your old filter has some information molded onto it. What is that information.
Could this maybe be an '87 original filter?
Here's what's mentioned as NOS for an '85 & '86 Corvette and catalogs actually mention '82 thru '87 for some
Here's a valve body diagram from an '87 FSM that seems to indicate it's the correct shape filter to be expected. I picked a random diagram - it's likely not correct for a C4.
she's a little clunky going into gear, especially reverse but pretty smooth once driving, still got life in her. Planning to switch to synthetic ATF and will probably do a second Chang in a 1000 miles or so to really make sure it's flushed then get on a regular schedule with it.

I'd avoid the "just any" synthetic personally but maybe the guys that do these for a living will respond.
On all of my AT cars I generally add a drain bung and rather than doing another "dump and filter" I'll do a couple of fluid drains and fills until satisfied that I've blended substantial "new" to the old. I do this on just maybe a used car purchase with no service history or a "high-miler".
For anything that used Dex III I use an Allison Fluid Transynd that's still Dex III certified. I use a product that's actually Fleetrite I believe from IH truck dealers.
This was a low budget driveable project for me. I was going to go with Mobil 1, that's what I use in boat's velvet drive and my Land Rover. But maybe I'll do a little more research.
Went with Mobil 1, fluid was low after putting back in what I drained, at least a quart or 2. When I pulled the pan almost all of the screws were barely tight and very gummy all around, so she leaked some at some point. Quick test drive and she was shifting smooth, need to top off tonight and we'll see how she holds up. No signs of any leaks this morning though so it looks like I got everything torqued up properly.
There was a change in the filter configuration back in the '80s to move the filter opening from the top to the bottom. That way it would still have suction even when the fluid was low.
Correct 1987 transmission filter?
