02 Tahoe vibrating between 20 and 40 mph

[rhschumaker]

I have an 02 tahoe with 128K miles on it. Just noticed that when car accelerates its vibrating between around 15 to 40 mph then it stops once it shifts over 40. no vibration at higher speed, don't hear anything per se and when I put it in 4Hi, there was no vibration at all. Guessing transmission and having to do with lower gears? Expensive to fix? This cars gotta last so any help would be appreciated. Thx

Stock or aftermarket wheels?
