Does anyone know the difference between part # 31259-A and 31259-B? I called the mother ship and got the part # for my original cooler and it is the B. I have found a remanufactured one but it is an A. Help please.

It has been long ago but it seems like Garry O had a similar problem and had to pull the control module out of the bottom of the trans and have it repaired. In my search I haven't been able to find the old thread that talks about his trouble yet.

First mention:
Transmission Trouble in Omaha

Full topic:
A very rare transmission story

Some mention of the module, but also note that there was a section of retarder housing gasket missing.

Well, problem solved! The problem was the aftermarket cooler from icebox diesel that I installed shortly after buying the coach.

Thanks to Rudy Legett for contacting me and putting me in touch with Expert Transmission in Huffman Texas. These guys are who you want to deal with, super nice and very helpful on the phone. I highly recommend them.

My suspicions were right all along, the cooler I bought just couldn't handle the load. While explaining the issue to Jerry at Expert, he told me that they just happened to have an OEM cooler on the shelf. They are only 4 hours from the house so the DW and myself got in the car and drove over and picked it up. Problem solved! Tranny runs nice and cool now and I am thrilled.

United Engines in Shreveport La. charged me $3500 and couldn't figure out the problem and they are an Allison Distributor. Also One Way Diesel in Nac was of no help. I'd stay away from these businesses if I were you. Thanks to all on this forum who responded on this thread, my coach is fixed and I can use it now, hopefully we will see you on the road somewhere.

MIke,

We really appreciate members who come back and tell us the final "end of the story" on threads like this.  You not only satisfy all the armchair mechanics (like me) who endeavor to learn something from other people's experience, but you also repay the members who jumped in with suggestions - whether they were helpful or not.  One of the great benefits of this Forum is always having people available who want to help - no matter what the problem.  We may not always have the correct answer, but we do the best we can.  When you take the time to tell us the final solution to your problem, we all benefit from the additional collective wisdom.

PS:  Looks like John44 (Reply #45) wins the prize for "Best Suggestion".  ^.^d

It is my intention to help others also. Hopefully this tread will save someone the headaches and expense I went through.

Sometimes the process of elimination is the answer and letting us know the good and bad places helps.

Glad you got it resolved. Ive always felt that a larger cooler would help in extended Retarder use. In looking at the manufacturers web page they do make one size larger cooler.(Longer) If I personally was replacing I would attempt to go to the larger cooler. It gets stupid hot here in southern nevada and a little more cooling has been appealing to me. Would require a different mount also. The new coolers are also three piece aluminum. This may be good or bad, I dont know. Think I'll run what we have for now. Thank you for posting your resolution. Glad to know im not the only one to induce my own problems, but with good intentions.
