first thing thank you for any help you can give on this. the van in question is a 1997 full size van with over drive (switch on dash) the reverse stoped working . all other drives forward work fine. a friend said that the rear overdrive unit is the cause! just with the cost of the drive i would like to here from others that had the same problem......thanks again rick..

 

In my experience, which is limited, when reverse goes...the forward gears are not far behind. You are probably looking at a rebuild.

 

agreed

I would get the rebuild done before the forward gears go though because you might not need new planetary gears... yet.

 

Hi Rick
Welcome to DF
The overdrive unit does not house the reverse piston. The main transmission case does. You need to remove the transmission pan and inspect. You can have the reverse strut that fell off the reverse band or the piston broke and can not apply the reverse band.

 

UPDATE THIS FRIDAY WE TOOK IT OUT ORDER THE TRANSMISSION KIT CONVERTER AND PULLED IT APART WELL THIS IS WHAT WE FOUND IN THE TAIL OF THE TRANSMISSION WHERE THE OVER DRIVE UNIT IS A SNAP RING BROKE AND THE PACK CAME APART, SO WITH THAT WE MAY HAVE GOTTEN AWAY WITH JUST CHANGING THE TAIL BUT WITH THE KIT IN HAND WE DID IT RIGHT AND IT STILL DRIVES AS WELL IF NOT JUST A LITTLE SMOOTHER THANK YOU ALL FOR THE HELP WITH THIS ......WE WONT FORGET YOU..:icon_ worthy::ico n_worthy::i con_worthy: :icon_worth y::icon_wor thy::icon_w orthy::icon _worthy:
