reverse doesn't work in 904

Hi Steve. I hope I can help. Adjusting the band is easy especially if you have a lift to get the car up on. Just drop the pan and the adjuster shown in your manual has an outer locknut that should be backed off several turns so that you can torque down the inner screw to 72 inch lbs. Of course you'll need to get a inch lb. torque wrench to do this. The inner screw should then be backed off 4 turns and the locknut locked down carefully so as to not allow the inner screw to turn any.

BTW: Just to get a feel for where it was adjusted at I allways count the turns it takes to tighten it to see how close it was to the proper adjustment. If it is close chances are the adjustment isn't going to help and your problem is elsewhere. If it's loose it's quite possible that is your problem.

Also if you find alot of friction material (will look kinda like grey mud) in the bottom of the pan that's not a good sign.
