Hard shift

1.Guys i saw post somewhere about tranny shift hard from R to D to R. And when i park car is moves 8 -9 inches back and forward. Axle or something maybe involved there.

2.And another shifting problem i have when iam driving, but this one i think because of low power. You can go on my post NO CAT and you can see what iam talking about. I really like my Impala but sometimes you have a porblem that even dealer cant find it and you have to spend your money to fix that.

What you think about question 1 and 2. I think they too far from each other.
Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What year car and what type transmission?

If it's an older, pre-1987 B-body with a 700R4, the harsh-into-gear is common. Beginning in 1987, these transmissions were fitted with an auxiliary valve body, which contains an accumulator to soften the into-gear shift.

A high idle speed can also cause this, so rule that out first.

Possibly worn CV joints? What condition is the fluid in, and is the Service Engine Soon (Check Engine) light on?

What is CV joint? Fluid is good. No light.
First i thought its strut mount then i chaged them.
I saw forum on similar problem but cant find it.

The CV joint is the constant velocity joint in the axle shafts (or half shafts). They do the same thing that U-joints do in a RWD car. If they're worn, there will be some slop in there and could cause the issue that you have.

How much all this operation gonna cost? And hwo can do it?
Thank you
