Hi to alls
Would someby have access to the serial number historical record of Borg Warner DG 150 and 250M automatic gearboxes (mounted on Jaguar MK 2) ?

Hi,
Coventry Foundation recently posted to try contacting a Studebaker Club in the USA for info about the Detroit Gear transmissions.
Studebaker cars were the first to use DG trannys.

 

GG is asking a hell of a lot as DG 250s were used in a multitude of Jag models.
I think the earliest use was in the MK7 and onwards to MK8, 9 etc
Was used in the MK1 as well as the MK2. and onwards to the S type etc.
Perhaps GG could be more specific in his question about DG boxes?

 

I hold a register of S Types which includes a lot of DG250 gearbox numbers but they are not in any order so I am not sure that the serial numbers for any DG250 gearbox would give you a lot of information.
On the S Type the serial numbers start with JBC but the numbers jump about all over the place. I have a 1963 3.8 S Type with JBC17387 but then it jumps to a 1964 3.8 with JBC16155. This might be down to the registration date rather than the manufacture date. The oldest S Type gearbox number is somewhere around JBC30254 which is an early 1967 car before they converted to the BW35 which has a serial number similar to FG2740.

I would assume that all the DG gearboxes are sequentially numbered but as DG250 was used in the Mk2 and S type at the same time 1963 to 1967 I do not know if there was a separate set of numbers for the Mk2 and then another set of sequential numbers for the S Type just like the numbers on the engines in the two models are different.

 

What you can do is look here: SALOON Data - Keeping track of every Classic Jaguar Saloon - Jaguar, Daimler classic saloon (sedan) information, articles, photos and register
You may have to look at the individual cars, but the ones with a chassis number ending in BW are automatic cars.
The earliest Mark 2 I see there with an automatic and numbers given is a 1960 car, the 126th built. The transmission number is J3B5652

The build records at Jaguar would have this information, but they will not let you browse through them.

 

Thank you to alls for your inputs, especially Jagboi64, for SALOON Data - Owners - Jaguar, Daimler classic saloon (sedan) information, articles, photos and register
My best regards
