Recommend a trans shop..

I believe the 4L80E in my 06 2500HD GMC is going.. started out it threw a CEL, code was trans component slippage. So I dropped the pan fluid was clean not burned up.. tossed in a new filter and fresh fluid.. light still comes back.. I had heard the speed sensor on the trans can go bad and cause this so i replace them just to be sure.. still there. i can clear the light and drive from westland to Taylor 275-94 and it wont come on til the trip home sometimes 2 trips but once i drive at freeway speeds and get off to side streets it shifts SUPER hard until i shut the truck off and start it back up.. I took it to a trans shop recommended by a co worker and he told me its the Torque converter lock up.. and i could have them replace the pump, converter and solenoids or just have it rebuilt for a little more.. anyway that co worker no longer works there and for reasons I wont mention i don't trust his word or his recommendation of the shop.. I have no interest in tearing the trans apart my self and id like to get another opinion.. maybe a shop that will actually test drive it?

Rich redid the 4L80E in my old plow truck. Worked flawlessly after and he even took the time to show me each piece that I burnt up. One of the best around trans guys around!
