Whats up my fellow coal rollers! New to the site just figured id ask a question to see if I could get some help. Got a 99 2500 cummins 4x4 and im havin a lil trouble with the transmission it seems to hesitates in a few gears and especially in 3rd under a lil bit of load and drops in 4th and seems to lose a lil power beforepickin back up. Any help would be awesome!


Thanks Jeremy

 

Fill out your sig. Is the truck modded? How many miles on it? Hesitates how? Does converter slip or shudder? Sorry I answered your question with lots of other questions but it might not be tranny related at all

 

minor mods intake/exhaust, it hesitates as in if too much throttle it almost feels like it doesnt want to go in gear have to hold around 1500rpm for it to shift and after it shifts into 4th it falls on its face its not a nice smooth shift.

 

Welcome..is it lockup coming in at aprox 50 mph.. if you are not into throttle it will feel like you just lugged out with low power..i would check your tv cable adjustment..good luck pt

 

Basic maintenance and adjustments done? Fuel and air filters? APPS reset and relearn? Might need to adjust the bands in the transmission. For the cost, it wouldn't hurt to take it to a trans shop, have them flush, adjust, and check pressures.

 

yea just got a new intake, fuel filter was changed out a few months ago, the apps reset and relearn i have no idea, but the bands needin adjusted might be the problem ill take the advice and go to a trans shop and see if they can figure out exactly what it is thanks RA could u give me a lil more info on the apps reset and relearn tho id gladly appreciate it.

 

APPS Adjust:

Relearn is very simple, and to be done after the adjust:
1, Disconnect both battery negative terminals for half a hour, then reconnect
2,Turn key to run postition, but do not start
3, Slowly, taking 3 or 4 seconds to do so, depress the accelerator pedal all the way to the floor, and slowly allow it to return to the top, taking another 3 or 4 seconds.
4, Turn key off and run as normal afterwards.

 

thanks again!!
