Was having a really hard 1-2 shift after truck was warm. Thought I needed a new transmission. Bought this as a last resort, installed new and inspected old one.Looked as though it had old black fluid still in the stock valve body. Replaced with new part and truck shifts like it should. Smooth shifts and no more hunting for 4th gear or TC lockupA little more expensive than the parts rebuild kit, but install time is about 2 hrs start to finish. If I would have just bought the parts kit I would still be working on the truck and not writing the review.

Not super aggressive shifts. It seemed like it took a few miles to see some benefits on shifts. Good for a stock truck with a tuner

Works great, used this in my 98 expedition 4x4 no issues. Super easy to install. I didn’t have any issues with my previous part but since I was reading info on the types of problems they can have thought it would be best to do it before there are. The 1-2 shift is firmer less lethargic feeling the 2-3 will shift fast enough my serpentine belt slips at WOT. Recommend it highly to anyone with a E4OD/4R100 that wants to have a firmer crispier shift.

Well this seems to have fixed some problems I’ve been having. It works for sure. I’ve only driven ten miles. But by comparison it shifts like butter but nice and firm by comparison to the old one. I had a problem where sometimes I wouldn’t have 3rd and it would shift into neutral instead. Hopefully this fixes it I’ll update later. No complaints so far

2004 F350 5.4L Triton 193KSymptoms were failed 1-2 shift with hard shift into 3rd and no overdrive. I bought the upper/lower main valve body and did them all at the same time. Good thing as I had a broken spring in the accumulator and the lower valve body. If you're going to open the transmission, do them both if you can afford it.

Super easy installation, and worked perfectly for fixing my harsh 1-2 shift that was caused by a broken accumulator spring.
