Shift RiteTransmissions Replacement for 4R100 96-04 HD HP 4R100 Accumulator Body Sonnax Transgo Update Valve E4OD Transmission Compatible for Ford 4R100

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.

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.

Perfect fit, easy to install. Shifting like new!!

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

Transmission has never shifted so good!

My f350 7.3 shifts very smooth very happy

If it's a rough shift you have this fixed it my 99 F250 7.3 l shifts like new

my 1997 Ford Expedition had been shift extremely hard from 1st to 2nd gear and this product worked amazingly!!!! After installing this product the hard shift went away and now the vehicle shifts like new!!!! Definitely recommend this product!!!
