transmission problem plz help 48re
 

my 06 cummins just developed a problem last night, i just installed a black maxx programmer on it a few weeks ago also,i have only tested it and turned the truck back to stock since the truck is stock as far as i know. I bought the truck 2 mnths ago with 92k on it and now it has 94k. my problem is it is shifting from 1st to 2nd like crazy when taking off ,even if i baby it or mash on it it does it... everyother gear seems to work correctly. oil is still red and clean, any ideas would be great

Common issue, It's what they call gear hunting. Dealer can change the actuator and reflash the transmission control module for around $150.

whats the name of this actuator? can i do it myself?

Governor pressure sensor is what it's called. You can replace it yourself fairly easy, just need to get a new filter, pan gasket, 6 quarts of ATF+4 (parts store carries the ATF), new o-rings, and a new gasket that goes between the governor body and valve body.

ok thanx. anything else i should know?

Might as well adjust the bands

The front (kickdown) band adjusting screw (2) is
located on the left side of the transmission case above
the manual valve and throttle valve levers.
1. Raise vehicle.
2. Loosen band adjusting screw locknut. Then back
locknut (1) off 3-5 turns. Be sure adjusting screw
turns freely in case. Apply lubricant to screw
threads if necessary.
3. Tighten band adjusting screw to 8 N·m (72 in. lbs.)
torque with an appropriate Torx™ socket.
CAUTION: If Adapter C-3705 is needed to reach
the adjusting screw, tighten the screw to only 5
N·m (47-50 in. lbs.) torque.
4. Back off front band adjusting screw 1-3/4 turns, for
diesel vehicles, or 1-1/2 turns, for V-10 vehicles.
5. Hold adjuster screw in position and tighten locknut to 41 N·m (30 ft. lbs.) torque.
6. Lower vehicle.
REAR BAND
The transmission oil pan must be removed for access
to the rear band adjusting screw (1).
1. Raise vehicle.
2. Remove transmission oil pan and drain fluid.
3. Loosen band adjusting screw locknut 5-6 turns. Be
sure adjusting screw turns freely in lever.
4. Tighten adjusting screw to 8 N·m (72 in. lbs.)
torque.
5. Back off adjusting screw 3 turns.
6. Hold adjusting screw in place and tighten locknut to
34 N·m (25 ft. lbs.) torque.
7. Position new gasket on oil pan and install pan on
transmission. Tighten pan bolts to 17 N·m (13 ft.
lbs.) torque.
8. Lower vehicle and refill transmission with MoparT ATF +4, Automatic Transmission fluid.
