What is this part and what does it do? ( Borg Warner 35 BW35 )

[4age_fun]

If anyone knows what this is and the correct adjustment for it could they please let me know. Its a borg warner auto trans from a 1974 Toyota Crown. I am hoping its something to do with the bands as they are due for an adjustment.

Thanks for the information but do you know if the part in the video is the rear band or front band. Thanks

[madmont]

That was the front band adjustment the rear is adjusted externally

[4age_fun]

Thanks for that. Does the band in the video appear to loose?

[madmont]

Hard to lell without using the spacer

[4age_fun]

Oh ok just one last question. Where is the location of the external adjustment screw for the rear band?

Thanks again for your help madmont.

[madmont]

it is on the drivers side of the case on top of the rear servo

Where is the location of the external adjustment screw for the rear band?

Look for a large stud that has a small square or hex head on it, with a jam nut against the case, maybe also has a washer.
DON'T over torque it!!!!!!
