TH400 WOT will not leave 2nd or go above 4500rpms
My Th400 will not go into 3rd gear and in 2nd gear at WOT it hangs at 4500ish rpm and 12lbs boost like it is just hitting a rev limiter...
Help me with some ideas on troubleshooting?
Shifts fine 1 2 R, fluid level ok, hasn't been above 150 degrees

Can you give us some more info on what work/parts have been done to the trans?

It hasn't been above 150 degrees temp with the big daddy derale cooler on it. I also used the transgo check ball kit so my vacuum modulator wouldn't see boost. One thing I didn't do was a pressure test on the transmission.....
I am going to pull the governor to see whats up then likely pull the pan looking for shards of metal this weekend.
Might be time for an upgrade... I see FTI TH400's on Summit for like 1700 w transbrake

They usually keep the level 4s in stock, if not I have all the parts in stock and I can have one built and ready to ship in 2-3 days! If a trans brake is your ultimate goal then that's the definitely the way to go.
