Anybody have any info... are all the '69 th400s the same? I need an answer ASAP!
This PW th400 came out of a '69 Grand Prix that had a 400-4v. I plan on matching this trans with my '69 400-4v as well.
I understand the "P" prefix part of the PW stands for Pontiac, "B" is Buick, "O" is Olds, "C" is Chevy, but I didnt know what the "W" was unless it was simply body style. If the PW and PX are exactly the same except for the trans tag, no big deal.
Im just checking as I didnt know if there was a difference internally for the th400s that are used in Firebirds, GTOs, Grand Prix, Buick, Chevelles, Camaros, etc.
Any information in the next hour...would be greatly appreciated as Im driving a few hours north to look at this PW th400 and likely buy it. (Great deal of $150 for the trans and converter coming from a low milegae '69 GP where this was just removed last week.)
BOP th400's are the same with the exception of the short vs. long tail shafts. The "W" is a body code designation and as you stated came from a Grand Prix. I've got a 74 buick th400 in mine. Had to swap out the long tail shaft for a short and bolted right in. There are two types of vacuum modulators, one is stight out the other is bent. I beleive the cheby's are a little different (bolt holes?)but BOP are the same.
I picked it up a short time ago and just got back home. Its a short tail PW-69-#### th400, (still has the tag), and the guy said it came out of a 69 GP, just removed a few days ago. He was parting it out.
I got the trans and stock converter for $150. Its grimey, as is to be expected from a trans that was just in service, but splines, seals, casing, etc, all look good.
It now goes in storage...just like the rest of my parts...till I can work on it again...
