727 lost reverse

[phantom]

Hi.
Pulled my car out today to wash it, but as soon as i put it in reverse to turn it on my driveway, nothing happend. Worked fine yesterday. Think i heard a small noise when i put it in reverse, but im not sure, as i wasnt really listening for uncommon noises. Drive works fine  

Did some Google-ing, looks like the reverse servo piston can crack?

lost the servo - can be rebuilt by you or a shop

Could possibly have broken a low/reverse band, I had that happen on my 74 Dodge pickup the trans had a fairly stout shift kit in it and when you put it in reverse it would usually go into reverse pretty hard especially if the engine was cold and on high idle.

Found the problem. This was laying in the pan when i took it out.


Read that they could come loose if the band was too loose? So i re-seat it and tighten it, right? Anyone know the torque- specs?

Edit: Youtubed it, see now that the adjuster nut was too loose, so it fell out. Need to re-seat it, torque the nut to 72 inch-pounds, or 8,16Nm in my language
