Mk 3 Auto box

[rcoups]

Car was coming along fine, just had to do the brakes (nothing there at all) so decided to move it on to flat ground. Reversed out and then into L and it wouldn't move so I tried D and still no movement. Any ideas?

[harvey]

If the selector linkage is working as it should, and the fluid level is correct my next question would be have you still got drive in reverse? If so then you would have a fault with forward drive only, which is normally front clutch related.

I have another box from a V8 so I could change the bell housing but would the linkage be different or is there any other gearbox that will fit the car. If not I suppose I will have to do a grand strip down and refurbish it.

The box used in the V8 is a six-position box, whereas the 3 litre only has a 5 position, so to fit the V8 box you would need to interchange the valve block. I would guess that the selector lever on both boxes would be in the same place, as well as the dipstick tube.

Look further into the problem before considering changing one faulty box for what is possibly another one..........

If you do attempt an overhaul, there are certain tools that you can't get away without using.

OK thanks Harvey

will a dg box fit a mark 3, the mark 3 is a 1966 car the dg box will come out of a c reg car or hopefully it will be a late 1965 mark 3

No the mountings/linkage/inhibitor and lever positions (PDRNL) are all different as well as the engine (cam, crankshaft and flywheel)


All MK3's had the same BW35 box with front pump PRNDL (unlike the P5B version which had the D1/D2 L or D1,2 shift)


The BW35 is cheaper to repair and far more common anyway
