4r100 trans FIPL??
Having downshifting problems with REbuilt transmission. Is there a FIPL sensor for the 4r100? I was told to check all engine codes first, but i just have a EBPV sensor code, but removed the valve when I installed the GT38R turbo...
Any help would be great. Thanks!
Rebuild:
- Tugger kit
- triple disc Billet torque converter
- New clutches and seals,.
- Banks Trans command module
... I also have a 6-pos tuner..
I had a Super chips tuner too and it has ALWAYS had the downshifting on acceleration on up-hill grades!! so i didnt think it could be the programmers

WHAT???...
The positive has been that the transmission seems to have GREAT line pressures and shifts smoothly in all other applications except accelerating getting on the highway ramps, or cruising down some Tennessee back road that has a gradual hill that causes it to downshift until it reaches the top.
Thanks for the feedback!!... I know that Transmissions are not really a cut and dry solution with forums.

Mark worked on the 4R100 program when he was a transmission engineer at Ford. Regardless of what you have been told elsewhere, Mark's information is accurate. You would save yourself a lot of time and money if you forget what else you have been told about the 4R100.

The transmission downshifts on acceleration either during a gradual climb, especially when merging on the highway. It runs great otherwise. Its just annoying if its a long hill, because it will do it until it reaches the top... What is funny about your comment, is the Trans shop that worked on it, is the one that told me it was probably the FIPL?..
I was told to take care of ALL codes first, which is only my EBPV sensor and high press...thats it??!!

I was wondering if there is another transmission that is VERY similiar to the 4r100?? that they put on the Powerstrokes?... This downshifting problem started when the trans was rebuilt.. Thats why I thought it was a Torque converter... but the transmission fella's that told me to clear ALL codes first, told me that TRans shops will do anything to make the buck and that he thinks that's why put the "Tugger" shift kit, they probably messed up either drilling or wrong spring,that with a good Electronic tuner they could have made the trans work great, but they then wouldn't make more money off me!

I guess the key word here is that it "cycles" between gears on acceleration(downshifting)..if its 3rd gear it cycles between 3-4, if i floor it, it starts cycling between 2nd-3rd... I will trouble shoot more!
Thanks for the info!

The Banks Trans Command is suppose to help reduce the downshifting by increasing the fluid pressure thus holding the higher gear longer before a downshift is required. I'm not a techie so I hope I got this explanation right. ~ Bugjr ~

The trans command CANNOT reduce downshifting. The downshifting decision is made in the PCM, not in the transmission. All the trans command can do is affect how soft or harsh the shift is. It cannot change when the transmission shifts.
