My torque convertor started whining, and eventually wouldn't lock up anymore after a few days. The transmission shifts and truck moves slowly, but it feels like the TC isn't transferring power from the motor through the transmission. I got the transfault error with blinking OD light, and a p1744 code.

I replaced the trans filter and did a fluid flush a year ago. No leaks since, and fluid level was good when it started acting up this week. Truck only has 65k miles.

So, I purchased the deluxe rebuild kit from Rock Auto. A Hughes Towmaster convertor from Summit. New solenoids. And now I'm stuck as far as what shift kit to get. Any advice? I can't find what the valve body differences are between the 4r70w and my 4r75w. This is the kit I'm looking at, since its specific for a 4r75w and F150. But there are plenty of other kits for $60. I already have an SCT XCAL3 with increased shift firmness from VMP.

Great how to for anyone looking to rebuild their transmission themselves.
