Hey folks.I am having an issue with a friend over my car. It is a 65 Cutlass/442 Convertible. It has the automatic (Jetaway) but I converted it to the 2004R for better Freeway gearing. He states that my car cannot be a 442 because it has 3.08 gears instead of 3.23's I keep trying to explain that there were at least three seperate gear ratios provided by the factory and 2 or more additional available from the dealer. Can anyone help me out with this issue? All Help is appreciated.

Looking at the 65 specs booklet, the jetaway 442 package Cutlass or F-85 had a 3.08 standard. If I'm reading this right, a 2.78 might have been an option. Sticks got 3.23.
Comes from a dealer that sold a roller 1965 Fremont 442 that of course has no 4V code. This is how they determined it to be the real deal.
"The 4 mounting holes are present. The frames "ARE" different... A true 442 has 4 holes where the rear-end upper control arm bolts to the frame (note: 10 bolt rears are in the 3rd hole from the top, 12 bolts are in the 2nd), the non 442 has only 1 hole. This can't be counter fitted without cutting and welding connecting points to the frame or trying to accurately drill the other holes."
Fremont build throws a wrench in proving 442, but the 65 CSM indicates 3867 V8 Jetaway could have come factory equipped with either of two 3.08 gearsets depending on tire size (442 had 7.75-14 tires), 3.23, or 3.55. All ratios were available either regular or anti-spin.
Cars with 15" wheel option had the same available gearsets.
Tell your friend find a 1965 dealer car order form and look it over. GM was only too happy to offer customers a choice back then and some judicious checking of the car order form could produce some interesting cars.

Here is the info directly from Oldsmobile, and as usual it's conflicting. The SPECS booklet says that 3.08 was the base axle ratio with AT in the Cutlass models (it does not break out the 442 option separately).
The special 442 brochure on the other hand shows 3.23 as the lowest numerical ratio with the 442 option and AT.
Of course this is a Fremont car, so the 4V code won't be on the cowl tag. For 1965 cars the frame is probably a more reliable indicator. It's too bad the original trans is missing as the HD Jetaway used in the 442 carried an "MK" code.

Hey Joe, this is [only] for the 65 442 as you said correct ? My frame on the 66 442 is not like this where the trailing arm is attached...
in '68, I had a '65 442 Conv, (Midnight blue met w/powder blue int. ) it was a 400, 2 speed trans and 355 gears. car was Loaded, AC, PW,Pb, PS. the trans even had a factory shift kit in it ! Judgeing it by the rear end "gears" is totally Lame.

My 67 has 2 holes. The FSM says they are chosen by transmission type, auto or manual.
The upper control arm angle affects the instant center and how it reacts from a dig.
No, reason why I swapped is because a trans shop threw away the Torque convertor so the tranny was essentially useless to me to keep.
Yeah, except for that pesky MK code that would have helped to authenticate your car. Another reason why I've always tried to keep every OE part I've taken off my cars.
