Possible trans problem or not???

[jway]

The problem start about 4 months ago. The problem is my 2000 chevy blazer is started and put into drive. I will depress the gas and will get going. To a point.... At 15 to 20 mph the blazer will start to sputer and remain at that speed. Then I will slow down quickly or slowly (doesn't matter how fast) and depress the gas again it will run fine. The only other time I will have a problem is when I fully accelerate the sputering will slightly come back and wont shift very easily. I have replaced the fuel filter and did a fuel cleaner already. I am looking for any one who might have a answer to this.

Welcome , don't know the mileage or recent things you've done, but quick checks- vac lines not rotted out check intake by PCV to the reservior and down (if 4wd) to actuator. Clean the MAF sensor in the intake with electronic spray or brake cleaner. Cap/rotor OK no tracks/arching inside. Depending on mileage plugs, wires, other sensors - any codes (SES light on?) need to post after free read at most auto stores. Let us know.
