a4ld no reverse with new VB

[adeelregina]

Hi,
I got a rebuilt A4Ld value body and no shorts. Also transmission seems to work better than before.

Just a new problem. My reverse wouldnt kick in. By this I mean from OD to reverse or neutral to reverse. What I notice is that if I start the car from park after been idle it goes into reverse but really slow. Also I checked and guage the transmission fluid.

Any suggestion on what is going wrong with the reverse?

Thanks in advance.

To add to the above, when I drive it for a while and then leave it on park for 5mins, the reverse kind off kicks in but low pressure, as I mentioned earlier I have a rebuilt a4ld, now what could I have missed that the reverse isnt kicking in?

Thanks again

Thanks

if you remove the pan, rear passenger side there's about a 2inch or so diameter cover. that is the low/rev servo cover.

Hi,
Thanks for the useful picture. As far as I remember, I didnt put a seal or gasket in that 2" diameter, you think thats my problem if so, where can I purchase the seal and what is it excatly called.

Thanks a lot

Hi,
In the process of diagonising, I figured out that when my explorer is warm, reverse wont work at all. Although if the truck is left for park and switched off for more than 30mins, and I go to reverse, it works, but again low on pressure.

HI,

Thanks a lot
