Rich LaMonte

Hey all,
my name is Rich. I bought my first jeep just under 2 years ago. Its an 05 jgc laredo as the thread title says. When i got it, there was 114000 miles on it and It has 121000 miles on it now.
i have had an issue with acceleration starting at about 20mph and slowly speeding up to 45-50mph. Once i hit about 20mph the car starts to buk and shudder almost as it is out of gas. There is severe power loss with this as well. If i let off the gas for a minute then try to speed up again the shudder stops and power is fine again. Also if i step on it there is no shudder. When speeding up quickly like merging onto the highway the jeep sometimes will not shift. It will almost redline before shifting. Sometimes i can let off and step on it again then it will shift normal again. This onlynhappens once in a while but the shudder happens almost every time imdrive it. There are no fault codes at all.

Does anyone know what the issue may be? Or at least an idea where to start looking? Is it possible it is the TCM, shift selanoid, center console gear shift lever??
thanks

I know this may be kind of late but it sounds like a torque converter issue caused by contaminated trans fluid.
