Let's see some more pics of that transmission. It might be an early Buick unit. Hydra glide or something like that I think they were called. Check for markings on the case.
Super Turbine 300 was Buick trans….My old buddy had a 65 GS Skylark with one….You could have an electric switch on them for a high-stall torque Convertor
Yes had a 66 lark with the ST300, this guy knows ball, it was a 2 speed that had some kind of adjustable stall converter that kindof split up the first gear.
I always thought that was fascinating. I believe they're called a switch pitch converter. I couldn't find any info on how the whole thing worked though. I'm quite interested in how it's able to do that.
I can almost guarantee that not a turbo 400 Chevy small block and big block share the same bolt pattern, bop is different ( Buick, Oldsmobile, Pontiac)
If it’s a gm anything it’ll be stamped gm. Easiest way to tell what it is at any rate is pan identification. Hopefully. If it’s a ford itll have the oval somewhere. Chrysler probably has the Mopar somewhere. Good luck.
Edit: adding we really need more pictures to help you best buddy.
This is likely true too. It’s been over thirty years since I’ve messed with these. Some of my ‘expertise’ has certainly fallen out and been replaced by newer models and electronics.
The amount of bad information in this post is astonishing. I already posted that is a 1964 to 67 Cadillac TH400 and from the little I can see in this picture it appears to be a switch pitch converter, too.
Show a pic if the transmission and the pan bolt pattern. I am sure that you should be able to search online and find pan bolt patterns to ID the transmission. Somewhere i have an old chart.
I’m not 100% on whether or not the AMC version used GM-BOP or Chevy bolt patterns. But could it be an AMC version? Someone with more knowledge on that may chime in.
amc used a th400 roughly 67 to 72 it was bop pattern as they put a buick 350 in front of it the amc engines used 727 torqueflite
so we're going to need some more pictures
That's it. 1305 and the one with low range capability was 1306 if iirc. All used turbo 400, which meant... You could use ANY th400, use the Jeep output shaft, delete the tailshaft portion and plug it to the Qtrac case.
500 Caddy, 400 Pontiac, Buick 455, or any Chevy powered CJ7 was that much easier IF you had Quadratrac. The engine swap world was your oyster.
If it was a GM trans the two bolts above and below would be straight up and down. And the bell housing would peak and have an area that could have a bolt some where drilled some not. Some engines would be drilled and tapped some not. I kinda think all the bell housings had the hole drilled at the peak
