transmission problem

Hi guys I have a 97 Yukon GT I don't really know how to explain this please bear with me for I am a woman lol. When driving every half a mile about it seems that something in the trans bangs. It's like if the truck were skipping, not sure if its from the torque converter or something else. I was told there's some kind of computer on the side of transmission that may be bad, does this sound familiar to anyone. Any ideas or info would be appreciated, I just need to know if it sounds like I need a new tranny or if its a simple adjustment or something silly. Tranny fluid is up to par by the way. Thanks guys!

More metallic clang, or a clunk? You can expound on the one sentence description, because every half mile is probably not the variable. Accel, deccel, upshifted, downshifte...

Also, let us know how many miles are on the truck.

It definately is more frequent than half a mile, it happens I believe on accel, decel, etc. Definately a clunk and it has 108,000 miles

Most likely it's the slop in the slip yolk / drive shaft or rear axle backlash. Very common on all GM trucks.

I didn't know it was common on these trucks. What made me pause for a moment is backlash. You are claiming too much? And it doesn't whine?

I'd start with the slip yolk.

Especially if you have a 2 door yukon.

No it doesn't whine at all

And it is definately on acceleration
