I have depended on Jasper for heavy duty truck, bus transmission and rear end rebuilds for many years. I can say that I have never seen any defects in workmanship on any work they have done for me. Jasper was very dependable in these items, B 400R, 4R100, Dana 60,70 series, 6V92TT. The factory tour was great, wish it was longer, talked to many factory associates while I was there, they were the best, you have a wonderful group of caring people, no wonder you have great products to offer. Your products would rank the best. Your plants are the cleanest I have ever seen. Housekeeping is 100%. All people that do any kind of work in the Auto, Truck, Bus related fields should come to your plants to see first hand, on what a good product you have to offer. Would you please see that he gets it, as this is my hobby. I am a rail car owner and operator. I would like to come back to you plants soon if I could. - John M.
