Looking for a 1972 olds TH400 for sale?
does anybody have a 1972 olds TH400 for sale?
I have a olds TH400 from 1979 but want to have the correct yr for my car.
If all other numbers match on the car except the trans can it still be a numbers matching car?

In a word, no. If you want to get close by the year, that's fine, but in your case, a T400 is a T400. You can try to find a correct 1972 A-body 455 OD code transmission if you like. That'll get you close to what's supposed to be in there, but you know you're fighting the rest of the 1972 442/Hurst crowd to find them.
What code is the trans you have in there? Look on the square plate on right side of the trans.

Everything I've got shows the OF trans was last used in 1970 on 2-barrel non-cruise control 88s (no speedometer cable connection). Sure you don't have a 1969 transmission?
If I had to guess, I'd say you've got a Frankenstein transmission rebuilt by a jobber many years ago. Probably an OF case with a speedometer tailhousing. If it's working OK, leave it alone and start searching for a 72 OD as it may take some time to find one and rebuild it.
I understand the wish to have the right stuff in the car. My 1976 Ninety Eight had a 1971 transmission installed years before I got it, and I have often considered looking for a correct 1976 unit. There's a couple junked 98s in the yards here, but working 60 hours a week, I never have time to go look. Then who's to say the junkers still have their original transmissions or the right speedo gear? I have a dead 76 Custom Cruiser wagon parked out at the farm, but it has a 375. I guess I could have the extra clutches and all put in it to make it a 400, but I'd still have only a 1976 date code, not a Ninety Eight 400.
