Jeep Grand Cherokee 2004 : Shifts hard, Need Input (valve, gas, head)

[ShakyJ]

Just picked up this 04 Grand Cherokee Laredo V6 with 117k miles, automatic.
No issues, but when it shifts between gears, its a bit of a bigger jump than normal. Basically my head will move back and forward a few inches. If I press the gas while on the road to kick in the passing gear, the jolt is more extreme.

No grinding noises, nothing else seems to stick out as an issue. Just shifts hard. No issues when driving, very smooth.

Clearly it need some work and it could be anything. I need some education here to understand it better so I dont get taken advantage of by someone who says I need a while new transmission verses something that may be less.

It is worth it to bring it to a national chain like AAMCO or deal with the local reputable transmission business?

Thanks!

You are better taking it to a local mechanic. I have never had good luck with the national chains.

I would start with a few inspection items first.

What does the fluid look like? You can pull the dipstick and wipe it off on a clean white paper towel. It should be bright red almost pink in color. If not then it is burnt.

You can start with a fluid and filter change. If that does not cure the problem and the fluid is dark then you more than likely have an internal problem.

I retired from the business before your Jeep was built. Older models had a throttle valve cable that could be adjusted. I suspect that yours is electronically controlled but it may still may be adjustable. check with a local shop.
