hey guys just got myself a 1600 and it has a 3 speed column shift auto in it. Reverse has gone and I was told its the reverse band?

from some research I think the box is a bw35 but not 100% sure.

Anyone done a rebuild or anything on them? I don't wana change the box for now as in a few months il probably do a transplant but thought if its easy il fix reverse. can you do it from underneath with the pan off? or does the box have to come out?

If it's the reverse band, you won't be fixing it with the pan off....its a complete teardown, with box out, I'm afraid.

Depending on year it may be a BW or a Jatco 3N71B - if you can check the model number plate on the RHS of the transmission case....if it says X0410 for the model, it's a Jatco...it should have 3N71B cast on the case on the LHS usually too. I am not sure how to ID a BW, but if it's an Australian built 1970 onwards car, with the BW Automatic badge on the back of the car, under the LH taillight, it's probably a BW.

Best of luck....be careful where you park, so you can roll out easily without reverse....

Thanks for the info!! Haha yea parking on hills so it rolls easy
