1969 Pontiac Laurentian/Parisienne 4-Speed

Question

Poontiac

Hey fella's! New to the page. but i've been thinking of doing an Auto to Manual swap in my 69 Laurentian. i know these cars came with either a 3-speed or 4-speed, could anyone help to identify these transmissions? and possibly track down a clutch pedal/linkage assembly.

The Parisienne/Laurentian were based on a Chevrolet chassis and running gear. So start with looking for a pedal assembly/parts from a '68-70 Impala. Those parts will probably be easier to find than the Laurentitian/Parisienne parts.

Do you know what engine you have? A Chevy small block (327 or 350) or big block (396, 427, 454)? Typically there is an emissions sticker near the radiator that will tell you or on the air cleaner. If not there are numbers cast into the engine. You can readily tell the difference between a SBC and BBC but not necessarily the actual displacement without the casting numbers on the block or heads.

So if you are unsure of you engine, please take some pictures of the engine castings. We can try to figure it out for you.

The manual transmissions were either 3-speed or 4-speed units made by either Saginaw or Muncie (respectively). A Tremec 5-speed might also fit the stock transmission tunnel - especially if you want an overdrive gear.

      Hello, all. 
      I've lurked here for a while now and I finally made a purchase in early November. I'd been looking for a '63 Pontiac full-size for about 5-ish years by that point. I wanted a nicely presentable driver that I could learn by replacing/upgrading things as I went, plus it'd be a great bonding opportunity for my boys and I as well. My grandfather was a mechanic at the local Pontiac-Cadillac dealer, but the Pall Malls got him long before I hand the chance to learn much from him. I'm working on power steering at the moment, coming up north I think has shrunken the torque converter seal, so that's next and a few odds/ends this winter need done. I also bought a reproduction '58 plate with the name of the little baby we lost inbetween the two we have and got a '63 sticker for it. I also plan on some sort of small dashboard container for some of his ashes at some point. Meet "Jonah". Car has PS, PB, A/C and power bench seat with 74k miles. Thanks for reading!

      Greetings, I am from Priceville, Alabama. I have a 1965 Bonneville convertible. I bought it last year and started a major restoration on the car. Getting close to finished. I want it to be a driver, not a trailer queen. The car gets a lot of attention at shows. People really seem to enjoy it. There are more pictures in my profile, "about me"

      Good morning! Im restoring my grandfathers 1966 Catalina and needed some advice from the people down around Phoenix AZ. There are a couple of rust spots right behind the front wheels that I need corrected, headliner, rear window rust spots and id like to get the whole thing re-painted in the original Reef Turquoise. I was looking for shop recommendations. This car is my baby so I obviously value trustworthy places down here that will treat my car with the same level of care that I do. Being relatively new to the area I appreciate any advice you can give on places to avoid and places to seek out! Thank you!

      I've got a 1970 T-37 Tempest, which i recently learned through PHS is nowhere near original, so ive decided to swap the motor from a 350 2v to a 455, the 455 i purchased came with a TH400 attached, but is from a 1970 bonneville. The T-37 as of now has a TH350, So I guess my question would be what would need to be changed, if anything, to put the bonneville TH400 into the Tempest or would the TH350 handle the stock 455?
       
      Thanks, Sam
