Question 1993 500E tranny 722.3xx reverse problem

New on the site... my '93 500E tranny does not engage in reverse, but all 4 forward gears work great and very smooth. Came across Rusty's write-up on the repair of the B2 piston. It got me going since it seemes fairly simple to do. Then I realized that B2 might be for the forward gears.
The question is: does anyone know the reverse piston name and locations? and, like Rusty's write up about the B2 which can be removed without taking out the tranny, is a similar write-up out there for the reverse piston?

Any help much appreciated.

Bad news.Reverse went out in the wife's wagon. This is caused by the B3 band (I think). This isn't something you can fix DIY. Time for a new tranny or a fix on the old one.

Good luck,
Todd

This is from a Mitchell repair guide for 722.3 transmissions:

Reverse doesn't engage: Check plates and sealing rings on brake B-3 piston. Replace if necessary.
