03 Jeep Liberty, no reverse, came back for awile then lost reverse again. No codes. Replaced soleniod pack, found accumulator plate bent and distorted. straightened and replaced missing screws. I also replaced the three seals between the valve body and trans case. No help, still no reverse. What next? I have rebuilt several 727s before but never in a 45 RFE.
Thanks
Lee

From what I remember the 45RFE needs no electronics for reverse as its one of the limp mode gears and in reverse all electronics are off as its all mechanical and hydraulic. And it uses the reverse clutch and the low/reverse clutch. I remember some of them breaking the screws in the acumulator plate and leaking fluid internaly past some of the acumulators causing pressure drop in some gears. I would pull the valve body and and air test the reverse clutch as John said. Its a good idea to check codes also. You may have to pull the trans to fix it. Ron

The reverse and low reverse clutches are on in reverse. I would suspect the reverse clutches, fairly typical. Do yourself a favor and install a Transgo Kit which will come with a heavier accumulator plate for the VB, but most importantly will come with a spring and ball to replace the converter limit valve assy in the pump which will be worn out. Also, find a reputable trans shop to install an oversize switch valve plug assy in the VB, major wear there which will eventually kill the OD clutches. Yes, it is coming out.

A Transgo Kit will give you a new #14 and 15 FYI.

Thanks for the info, which kit, the 45RFE-HD or the SK-45RFE. Which one do you recommend?
