Looking for a transmission shop in the Houston area to take my GMC 2500HD to.
It's not broke yet, but it seems like something is slipping and I know nothing about autos. For example, backing up my parents driveway, not unusually steep, it won't even hold and will roll forward when in reverse. At idle in drive on a flat road, it doesn't quite go like the Ranger (granted the weight is a bit more).

Bought the truck wik 97000, now has 106000 so I don't know what previous maintinence has been done. I plan on at least having someone do a drain and fill, change the filter?, but would really prefer someone who knows what warning signs to look for instead of an NTB or such.

Thanks
