    I have a 1996 GMC Jimmy and everytime the truck is in 3rd gear (somewhere around 40-50mph) the truck seems to have hesitation or a sputtering feeling. When I accelerate up to 55-60mph that hesitation is no longer there. What could be causing this? The truck has 240,000 miles on but still runs really good and has a lot of power.

    When was the last time you had the transmission fluid changed? Also, is this the original trans and if so has it been rebuilt?

    It is the original transmission. Also, it has been quite a while since I have had the transmission fluid changed.

    Try having the transmission flushed and changing the fluid and see if that alleviates the issue.
