The front pump seal went in my E40D. Since the transmission is the original and has never been opened except for a filter and fluid change I figure I should just replace it with a remain unit. I found remain units for a decent price at Best Buy Transmissions and they have a 5 year warranty. I will be putting the unit in myself and they still warranty the unit but not the labor which seems fair. I just haven't heard of them before, I was wondering if anyone has used their products and how they hold up and the quality of their remain. I don't want to go with Jasper (I have heard horror stories) and I don't want to go with an Auto zone remain. By the way, I tow a 10,000 lb. camping trailer/toy hauler, there set up is supposed to be with a heavy duty torque converter and towing upgrades for around $1800. Any thoughts?
