Hey guys, does anyone know if I can use a 3 speed auto tranny from a 1965 Pontiac 326 engine to bolt up to a 1967 340 Buick engine??? Thanks! ray:
Yes it will bolt up, I would check the bolts on the convertor to the flywheel, some have large bolt pattern some small, some flywheels have both. But the bolt pattern on the case is the same on Buick, Olds, Pontiac and Cadillac. Chevy has a different bolt pattern all their own.
Supposedly it is a 3 speed, that's what the guy said. Haven't seen it yet. Maybe he doesn't know what he has??? He's only asking $40 for it.
i heard somewhere that the st300s were only used in buick and olds. if its a 3 speed then its gonna be a th400 because the th350s werent made till 69. :beers2:
Pontiac, do they still make them. o No: :eek2: At any rate, the 2 speed was used on the Tempest/Lemans from 64-69, same as Buick and Olds. Only it wasn't called an ST300. Like Buick/Olds, the 3 speed did not come out on the A body until the 67 GTO. So, it should be the 2 speed unit. Scott
It seems to me that it should be a 2 speed also. Probably gonna look at it tomorrow, are there #s to get on the tranny to figure out what this guy really has?
True the trans in a 65 Pontiac Tempest/Lemans/GTO should be a super turbine 300, but throught the years it is very possible that it has been swapped out for the same reason you are thinking of doing it.. A lot can happen in 44 years.. Easy to tell a th350 from a st300, the 350 has 13 pan bolts, the 300 has 14. The 350 has a square pan with one corner cut off. The 300 has two corners cut off and a section of one corner has a drian aid to help direct fluid to the drain pan..
My memory sucks but didn't the Super Turbine 300 have an electronic kick down that also activated the S/P where as the 350 has a cable? Also I believe some of the Pontiacs came with Glides. Maybe Canadiano No: The 1st 350s came out in 68 Bob H.
U R CORRECT.:bglasses: But there were two wires for the switchpitch and kickdown functions on the 300. But u r correct on the 350 having a mechanical kickdown. I believe they used a rod and not a cable, but could be wrong.ou: The Canadian Pontiacs used alot of the Chevy parts and I believe they used the Slides in the smallish cars (Acadians).:beer
I'm not sure about the early 350s I think they were cable but the Glides used a rod for sure.:beers2: Bob H.
Well, I measured my transmission's overall length and bolt hole spacing and went over to look at this guy's tranny. He told me it was a 3 speed, it was a 2 speed. He still had the whole dash of the car and only L and D on the indicator and I turned the gear selector by hand, yep 2 speed. Everything is the same on the length and bolt spacing. The car was wrecked with only 46,000 miles on her, so hopefully the trannys fine. I wanted a 3 speed but I got this one for $30!
Is the transmission u r getting from a Pontiac, if not what car did it come from? Reasoning, it may be switch pitch 300 transmission. Just look for two pin connector on side of transmission. (GM might have put the two pin connector on non-switch pitch 300's too, knowing them.) Get the model number off the plate on the transmission if not sure.
This tranny was from a 65 Pontiac Lemans and it only has a single pin on the driver's side. I checked my 67 Skylark and it only has one pin also, but there are two wires going down to the plug. These cars must have been prewired for the switch pitch tranny. Not sure???
