my truck (2001 ram 1500 5.9 2x4) just starting almost like jolting at certain speeds (45-50) it still shifts fine and if i floor it it comes out of the jolt but i cant figure out what could be causing this any help would be appreciated.

 

sounds like transmission or torque converter shuddering.
try turning Overdrive off and see if that helps any.

 

ive turned overdrive off and it helps a little but nothing drastic.
and my transmission still shifts easy and its only if im in a certain rpm at a certain speed range(45-50)

 

could it be anything to do with the injectors,fuel filter, anything cheaper to fix

 

anyone please i need help

 

Warped drive shaft, failing Ujoints, busted belt in tire, would be my guesses from the limited info.

 

maybe a bad TPS that would problemy show up on the tach

 

thank you any further help woulr be good it also liek bogs down when i first accelerate but its not a constant thing

 

fuel filter? better hope not that part of you pump. if it is you get to by a new one and drop the tank or pull the bed. i pulled my bed when i did mine but i put a goose neck ball in it at this time to, but it wasnt to hard

 

a skipping cylinder (misfire) will produce a jolting/shaking feeling under load.
often cured by tuneup with plugs, wires, cap, rotor.

you got any CEL lights or codes ?
