Automatic transmission rear engaging 'kick'
Hello 928 enthusiasts,
My 89 S4 makes a 'kick' when I engage the rear position. The previous owner told me that there's a dampening device available somewhere that cures this annoying problem. Since I'm going to change the trans oil & filter soon, I was wondering if this dampening device was difficult to install or if it's an easy DIY fix & if it exists, where to get it & how much it cost$$$$.
As anyone done this mod & is their any info on 'how to for dummys'?
Thank's!

Cannot remember if that impacts the harshness when drive or reverse is selected as it is so long since I tried without.
Bottom line is a vacuum line runs from the back of the inlet manifold to the gearbox and that must be connected or the change will be very harsh- same if the damper fails.
A fast idle speed will probably cause a harsh engagement [if that is what you mean].

I believe I might have what you are describing on my '88. From a dead stop you nail the accelerator and you get what feels like someone bumping you from behind. Interested in a solution or ideas also

I think the OP means he feels a jolt when he puts it in reverse, not a harsh shift between gears (modulator or vacuum.) But in the words of Billy Gibbons, I might be mistaken.

It's more than a 'thump' than a kick. It feel's like when you engage your lawn-mower tractor between reverse & forward; there's no delay or smoothness. It's not that harsh but it's annoying.
Do you think it's ok & can it be fixed?

Has the transmission ever been rebuilt?
