I am just wondering if anyone has replaced this TCC in the 4 spd auto that cause, a bogg or surge @ 60mph to 65mph.

TCC Surge/ Chuggle /Slip at 72-96 km/h (45-60 mph) with Automatic Transmission 4T40E ?.

I might have the same problem as you.It surges around 45-55 mph.Rpm fluctuates up and down.Mine doesn't do it all the time.Im thinking its transmission related. TSB# 01-07-30-026 Reprogram PCM. Here are some links with more info on it but I dont know if its the correct fix.It might have something to do with line pressure?
