some of the side effects are, When I accelerate the rpm meter jumps to 4000 rpm my truck jerks but doesnt pickup much, sometimes it wont go over 65 mph and I have to let my foot off the gas for it to shift to next gear (automatic) when i brake the check gauges light comes on the oil meter drops to zero the when i accel the light goes off and the meter back to normal
Any suggestions to fix one problem dont know if there related

you have two or three different problems with it,you need to take it and have the computer scanned on it first,then you,ll have some trouble codes to work with,without having this done you could spend a lot of money guessing at it,i see that happen every day to some people,good luck with it.
