I have a 99 34' motorhome with a 4R100 that has just been rebuilt. The problem mine is having is every once in a while I have to pull the gear selector down to first to take off. It fells like it does not down shift completely when coming to a stop. Trany shop put a new PCM in got alittle better but not fixed. Any ideas? I know this is not an RV site, but dont know where else to look.

 

Have them go through the trans again something is definatelly wrong
