What is the difference between the Borg Warner 35 box and the Borg Warner DG box, or is it just an age relelated model name change

Can you expand, I have not long bought a 1964 jaguar S type to go along with my P6 .Im not sure what box it is. The main differences in the operation from my P6 is that it has a anti creep valve that is set to the tick over and puts a pressure on thee rear brakes also has some form of gear lock so as to stop gear shift.

The DG box in my opinion is far preferable to the later 35 and 65 boxes,( and the Model 8 and 12 fitted to Jaguars ) although those later boxes tended to have a better shift quality . The DG ( it stands for Detroit Gear ) has the great advantage of a lock up direct drive in top, which eliminates torque converter slip and improves fuel consumption . The Jaguar versions also had the two alterations to which you refer - both developed by Jaguar themselves - of the anti-creep solenoid which traps a small pressure in the rear brakes until the accelerator is pressed , and even better the intermediate speed hold which means that you don't need to use kick down to get 2nd gear . You can easily tell the later boxes on Jaguars because they had the D1, D2 start facility, ( and no intermediate speed hold ) which locked out bottom gear in the D2 position. Utterly pointless in my view but Borg Warner were of course geared to the American market which often used 2 speed boxes - eg the quite appalling GM Powerglide
 
Hi, after a quick google, the DG box has a steel casing with a dipstick on the side presumably
accessed from under the tunnel carpet inside the car. The BW 35 box has an Aluminium case
and the dipstick is under the bonnet.

Hope this helps!

Hi Thanks for the detailed info, I am now convinced that the Jag has the DG box simply because of the the speed lock. Because I am a paraplegic ( wheelchair user) I will have to rely on others to check the oil position ect. The gear selaction is P,N,D,L,R.
