215 Buick V8. Wanna put it in a Model A truck.

 

A lot of cars using the ST300 were swapped to TH350s over the years.You could get a decent price selling that trans to someone do a resto.

 

Won’t bolt on to your 215,different bolt pattern.

 

D-2 did you ever make anything from that Jetaway Bell housing I gave you a couple years back... I got into the Turbo400 Hurst Autostick I shifter.. I want to put a switch pitch converter into it though...

 

I used it for measurements, but since the smaller coupling is using part of the bell housing, the bell housing is used for measurements for my 1955/56 Pontiac slant pan hydro to Buick 225 V6 (BOP) adapter plates..
If you want switch pitch, you will need a 1965-67 Olds TH400, or a 1967 Buick TH400. Cadillac and 65-66 Buick used switch pitch, but they have different bell housing patterns.
Pontiac never used switch pitch.

 

Pontiac had two different "Tempest-torque transmissions, as did Oldsmobile have two different Jetaway transmissions.
Both the later Jetaway and later Tempest-torque were ST300s. Pontiac did not use the switch pitch, and Buick/ Olds only used it till 67, with them going to no switch pitch for 1968. Perhaps the Canadians used the BOP/PG transmissions up there.

 

FYI, there is a 1965 Skylark in the Pick Your Part in Santa Fe Springs, CA: https://www.lkqpickyourpart.com/loc..._Santa_Fe_Springs-282/recents/?search=wildcat
This car has the 225 V6 and ST300 transmission in it as of 2/20/2022.

 

So my nephew just bought a 1966 Buick Special V6 and ST300 transmission. Does this transmission have the switch-pitch torque converter? The transmission control (kick-down?) switch at the carburetor has 5 wires connected to it --> 2-wire plug in the front and a 3 wire on the back. Thanks!

 

should have switch pitch. Study the switch and linkage carefully, see if you can figure out what it does. They're not all the same. The 65 Skylark I had years ago would go into high stall when you took your foot off the gas pedal, and low stall when you pushed on the pedal even a little bit. I think to keep it from creeping at a stoplight.

 

I had a 300 super turbine in a 68 Firebird - I drove that car for a decade in Los Angeles and it was a lot of fun... They are known for leaking from the selector shaft and it's difficult to cure. I put three or four new seals on mine before I got it to stop. Sometimes the selector shaft is marred or neck down, similar to the snout on a balancer.
