Replacing a pressure solenoid valve in the transmission valve body may fix an issue where the transmission "hunts" between first and second gears. Our technicians report that customers sometimes describe this complaint as surging or bucking.

Between 1st and 2nd gear the tranny doesnt seem to lock into 2nd gear. 3rd gear and on up shift fine.
I have a Ram 2500 6.7 Diesel automatic transmission. Sometimes when the truck is shifted from park into drive it will buck or try to accelerate forward, even against braking. The truck will die and then work well when restarted. Taking it to the dealer tomorrow.
Starts out in second from stop, then immediately downshifts to first and goes thru the gears normally after that. I replaced the solenoid and everything worked fine for ONLY 2,000 miles now it is doing it again... WHAT GIVES???
motor revsup to higher rpms but truck pulls forweard slowly and shifts from 1st to second very hard
Will not shift out of first or shifts hard
with a load tranmision strays on 4 gear
Will not change gears drives in first very
Slow the motor gets loud but will not go any faster.
Harding time shifting from 1st to 2nd
Shifts hard from 3rd to 4th. Stays in fourth sometimes. Turn engine off and it resets. Then shifts good until it heats up.
It hunt between first and second esp goin up hill and sometimes real sluggish take off
truck wont shift from 1st to 2nd unless going fast and left of accelerator pedal.And bucks in 4th gear at 55 mph of so.
At 45 mph keeps shifting between gears, up & down. I have replaced the transmission and torque converter
Hunting between 2nd and 3rd gears while trying to maintain a constant speed of 35 mph.
Replacement of the pressure solenoid fixed this problem.
It will shift in1st &2nd when cold but gets warm an well not go to 3rd & 4th.
my transmission shift out of first gear at high RPMs about 4000 and it jumps between first gear and second gear at low rpms
5.9 Cummins automatic. Found nylon clip on transmission that secures throttle wire to transmission pressure valve leaver not securing cable. Tried nylon ties but didn't last. # 18 gauge wire made it secure. Also plumbed in large Allison trans cooler with hydraulic hose and JIC fittings as the erratic pressure caused a leak in the factory cooler. Some modification to structual body supports required
Transmission will 'hunt' between 1st and 2nd gear with a load and at low rpm speed. All other shifts and operation seem to be normal. Fluid has been changed (not flushed) 3 times since 75k. Truck has a salt spreader and plows snow.
xmsn making knocking noise in lower gears 4&5gears very little noise
Not fixed yet, but we go down the road and at about 50 mph it shifts into its lower gear then shifts back up to a higher gear. Sometimes it stay in the low gear for about 5 seconds then it will shift to high again. And if you hit a bump it shifts sometimes too.
Hunts between 1st and second , rpm climbed way up before finally shifting into second gear
