RE: ALLISON 2000mh TRANNY PROBLEM, HELP!!!

After having a VP44 pump and lift pump installed on my 02" Journey at Turbo Diesel and Electric in Macon GA. I suddenly had a data link electrical problem which caused my trans check light to come on and the tranny went to "limp" mode. They did not have Allison software and denied that they caused the problem. Spent almost a thousand dollars at Middle GA Freightliner for diagnostics of data link problem that they could not find. (See RV Reveiws.Com) GA for whole story. Check Middle Georgia Freightliner and also Turbo Diesel Electric. AVOID THESE TWO SERVICE SHOPS, in MACON GA.!!! Now for the GOOD part of this story, I called W. W. Williams, Atlanta after getting screwed over by the fore mentioned company's, and they fit me in within three days, called me back almost daily status, provided a detailed cost estimate of not only what I brought the MH there for but also other things the found. They almost immediately found the data link problem, within one hour! Dropped the pan on my Allison found dirt in pan, cleaned/flushed housing, removed and overhauled the valve body, replaced some internal parts and internal harness due to age, replaced pan gasket, internal filter, refilled it with TES-295 and changed external filter. They determined the problem I had with check light and limp mode was due to a part of the data link harness was pulled loose and burned/shorted the cable when it came in contact with hot manifold probably at Turbo Diesel during the pump install. In addition they found a resistor end at another part of the cable had water in it, also probably done at Turbo Diesel Electric when they washed down the engine with water to get fuel they spilled on it. These guys did a great job

RE: ALLISON 2000mh TRANNY PROBLEM, HELP!!!

So far W.W. Williams Allison Service Center, Atlanta, has diagnosed a failure in the valve body. I assume they are rebuilding the valve body, it will cost me about three grand. They have indicated the top side of the trans is ok. Only 82k on 02" but they think a previous owner may have let it sit, will get more info next week. At least i am getting answers from these folk, they seem to be top flight.

Thanks to all that have shown interest in my ALLISON problem. For those that care to hijack the post, I hope you will refrain and get serious about assisting other RVers needing help.

ALLISON 2000mh TRANNY PROBLEM, HELP!!!

I run a 02" Winny Journey pushed by Cummins ISB 275, Allison 2000MH tranny. A month ago my VP-44 injector pump started throwing a check engine light and code. I took it to a shop and it turned out that I needed a new lift pump and the VP-44 high pressure pump. Some how the techs managed to do something to my Allison that caused the check trans light to come on and it would not reset when the ignition was recycled. I suppose the Allison was in "LIMP" mode because it would not do more than 45 mph and ran as though the torque converter was not locking up. Waiting for the opportunity to get it in the Allison shop in Atlanta. They said it was not electrical as most of their problems often are. Anyone have a clue what might cause the problem ?????
