jasper transmission WTF?!

[regalpainter]

I Replaced with a Jasper tranny, I was told it had 21 improvements over "stock" model.
Well I think it should have been 22, because it didnt last long. They replaced it, and two months later (today) my od lights flashed, limp mode for a minute, and ran ok after. I am going to test codes monday.

My question is who makes a high performance, long lasting, proven transmission. If this one craps out, Im going to ask for a refund, and I need help in direction......21 improvements WTF?!.........oh, my truck doesnt tow, plow, or haul anything heavy.

If you want a “bullet proof” tranny go to BTS; Brians Truck Shop

I went the "cheap" route and bought a factory reman 4r100 from Ford for $2035 with 3 year 75K warranty, and then put a BTS valve body ($225) in it and 2 trucool 40 K coolers ($120ea) in series and an external filter.
