Re: Allison 1000 02 workhorse w22
You may just need a firmware upgrade to your transmission control module. Any Allison shop should be able to see if your control module is up to date and correct it if it is out of date.
Also your engine control module, ECM, may be feeding incorrect information to your transmission.
Find a shop that has the proper diagnosis equipment and they should be able to pin point the problem without throwing expensive parts at the problem while you foot the bill.
