Denver area transmission shops?

[Martinjmpr]

Can anyone recommend a good transmission shop in the Denver area, preferably Southwest? Someplace that does good work, offers a warranty and stands behind their work? My 4L60E is having major problems - basically I've lost 3rd and 4th gears, the trans just slips in those gears.

I had to drive 110 miles from Kremmling to Englewood in 2nd gear, pulling a trailer. Not fun!

Thanks in advance for any recommendations!

ATS builds diesel trans and would likely do yours. They're pretty highly respected also.
