Weak John Deere 555 track loader

Pete J · Apr 23, 2012

My John Deere 555 track loader has little power until it warms up for about 30 minutes. After running it that long it has good power. The engine runs strong from the start, the machine just will not pull your hat off until it gets the transmission temp up. The transmission pressure runs in the low green all the time. I am about to change the tranny filter, but any other ideas?

When you change that trans filter, cut it apart to see what kind of crap is in the pleats of the filter..A bunch of metal or brass in the filter will indicate a possible major problem..

.Your dash gauge is NOT the transmission operating pressure, operating pressure is checked on top of the transmission case. TEST that pressure, F,N,R,1,2,3, cold, then hot, record the readings.
Compare to spec.
What Roy says is right.
But I have found There is a system relief valve threaded right into the pump. I've lucked out on some units, when that pressure was reading low, to set up or replace that relief valve, bought me a little more time/use.
I could never figure out why Deere didn't put a true transmission pressure gauge in the dash.
