2005 4.8is transmission shifting / slipping issue

[sroth004]

Thought it worth sharing in this thread I had Gary from AAA-1, who does the You Tube videos “upallnight” mentioned, work on my trans last year. Gary was thorough and very honest, had my valves tested by Ericsson Industries, which supplies ZF parts, rather than going straight to replacing components, the result being mine needed internal seals only, no hard parts. I share this only to let the group know that he is a great resource if you are in need of this type of work and geographically reasonably to his business. I travelled 7 hours roundtrip twice, once for drop off and once for pick up, and have no question about having made that investment in my time.
