Hy spanners, what is this transmission in, and is it stock to that vehicle?

i believe the trans is pontiac allthough not original it is about the same year (within 12 months)
its coupled upto a gmc/pontiac (GM7) 347 v8 engine number = A34715028
trans = CA-56 5899

its in what i,m lead to be lieve is a 1955 chevy 3100
VIN NUMBER = M255KO38183

i,d be very gratefull for any help as its a bit rare over here in the UK
thanks
mike..

p.s i posted some photo,s in GENERAL TRUCK TALK under WHAT WOULD YOU BUY

Hy spanners, I believe what you have is a two coupling type Hydra-Matic. In American motors cars they were called "Flashaway", in Oldsmobiles they were called "Jetaway", and in Pontiacs they were called "Strato-Flight", I can't find any shift adjustment spec's at the moment, but I will look for some tomorrow

just a ,bump, on this

i,m still trying to learn more

thanks,,

Hy spanners, here is a picture on manual shift lever adjustment, it's from a 1958 Oldsmobile sevice manual (same transmission), I hope this is what you wanted.

thanks 3B

that may help i,ll have to look at my trans and try the positions
as i,v also been told that i have a 4speed auto without a park position and that you have to place it in reverse with the motor stopped to engage park ???? do quite understand that bit myself
but the truck is nearly 100 miles away at the mo so i,ll check when i go over to her. or when i get her home

Hy spanners, the transmission you are now describing sounds like a Dual Range Hydramatic, which did not have a "park" position as such, but as you said when you placed the shifter in "R" with the engine shut off you engaged a park prawl. Unfortunately 1955-56 was the time of changes in the transmissions in cars, somewhere in 1956 most cars started being equipped with the "Dual Coupling Hydramatic". In Canada (where I'm from), our trucks never changed from using the "Dual Range Hydramatic", they used it right up to 1962. In my mind a "Dual Range Hydramatic" is a far superior transmission to the "Dual Coupling Hydramatic". It would help to know if this running gear came from a car or a truck (American GMCs used Pontiac V8s from the 1955 2nd or "B" series in their V8 equipped trucks up to the 500 series), so a little detective work on your part is required to verify which transmission is in your truck, hope that helps.

The HydraMatic transmission that was original-equipment in GMC trucks with the Pontiac V-8 had a large rectangular sheet metal side cover with the manual shift linkage going through it, along with a spring-loaded throttle position lever. It does not have a "Park" position at the top of the quadrant. The transmission used in the 56-up Pontiac, Cadillac, and Oldsmobile passenger cars was known as a "Controlled-Coupling Hydramatic". Depending on the specific carline, various names were used in advertising copy. This transmission had the shift quadrant which included a designated "Park" position above Neutral. The large sheet metal side cover was not present on that unit, and I believe it had an aluminum housing, not cast iron. It was not used in any truck application that I'm aware of.

hi,
i,m almost shure that the side cover is cast not sheet metal and it has two levers one coming through the middle of the other whitch i beleive is the throttle position lever .

so it sounds like it came from a car ,,

also the truck has what i beleive is a 12 bolt rear end with a removeble diff and a rear cover what we in the uk call a ,banjo, axle

Hy spanners, both the transmissions we have been discussing have the same setup as far as the manual shifter and throttle pressure lever shafts are concerned.
