Being new to every thing jaguar can anybody clear up what is a DG auto box , is it just a version of the borg Warner 35. I also have a Rover P6 with an BW 35 but never heard of a DG

Hi John,
The Borg Warner DG [Detroit Grears] box is pre BW35, I hope it is working
ok because it cost double the amount to fix compaired to bw35.

Regards Dave.

hi Dave
thanks for the reply, The gearbox is working fine I assume that it is the DG box, the only issue that I have is the anti creep needs sorting also this speed lock is not working

Hi John

If you have anticreep and speedhold you have a dg

I think the anticreep devices on the dg box often fail, I removed the solenoid underneath the car. Even when new there were reports of them locking up

I repaired the speedhold function on my car earlier this year and it is well worth doing, the previous owner had attempted this but could not cure the oil leak from around the solenoid that pulls the rod that stops the car changing up into top

If you want some help with this I can help

If you are lucky it may just be the wiring or the solenoid this is a reasonably easy fix and there are access holes either side of the transmission tunnel( at least there is in a mark 2) so you can just about get away with doing the job/ testing the parts without jacking the car up. Although if you can jack it up this avoids lifting the carpets if they are glued down. Testing the wiring to the solenoid is easy, just check you have 12 volts to ground with the switch in the in position and then check the switch turns it on and off, if there is no voltage you can test the solenoid by pulling 12 volts into the wire an listen for a click

Graham whitehouse auto transmissions and automatic choice were a great help in supplying parts and freely giving advice to help me fix the box. Graham said these boxes are very tough, more so than the bw 35,


With mine I had to take the tail piece off the gearbox as a couple of the seals in the box were missing causing an oil leak. This was a very worrying time as I new zilch about auto gearboxes

As I said well worth doing because the speed hold effectively allows you to chage down at the flick of a switch or hold intermediate gear when giving it some beans down the lanes or up a hill of when overtaking, obviously you do have to watch your revs all this means more fun

Cheers

Thank you again for the extra info regarding the anti creep and the speed locking devise. Unfortunately I am a paraplegic ( paralised from the waist) so as much as I would like to do the work under the car ( I do miss it) I now have to rely on other's but from my position I need to know what I am talking about when I talk to garages about work. All My adult life I have been a mechanical engineer (not Cars)and I have always had old cars and m/bikes in my life.
