Rough downshift bumping

[tom4bren]

You didn't mention if it happened every time you came to a stop. If it only happens sporatically, the AC compressor could just be kicking on at the most inopportune time. That would accelerate the engine while it's trying to downshift. It won't damage anything but it is bothersome when it happens.

Remember to keep your foot firmly on the brake while stopped. Several members have posted near fender benders because the VX will start creeping forward when the compressor kicks on.

The search term you want is....."Clunk" ....

and it sounds like it is just the normal clunk noise that a lot of us have had as we come to a stop. I believe the proper term is driveline lash.

Lube up the u-joint and the yoke on the driveline. That helps alot.

A tranny flush in combo with that may help as well.

It did NOT happen every time I stopped. I have drive vehicles with the compressor kick, but I am pretty sure that what I heard/felt was more intense than what the AC could do. So I am starting to think it might actually be mode switch or transmission fluid level / service.

FYI - This is a VX I am looking to purchase, and noticed the problem during a short test drive. I think the combination of louder exhaust, rough road, and the "clunk" left me with the feeling that the ride was somewhat more rugged than the other VX's I have driven. I'm trying to decide if all of this put together is telling me to stay away from this VX, despite it's color and low miles.

Thanks for all of your tips, guys!

Sounds like you should steer clear to me. Seems like VX's in all colors are popping up weekly on eBay and AutoTrader now.

I thought all VXs made that sound? Mine does, and drive the piss out of it, on and off road.
