an issue recently cropped up where my car drives perfectly fine around town, but if I stomp on it and give it the beans, there's a subtle vibration, almost like the front wheels are out of balance (they're not, I checked that straightaway of course!).
The car just came back with the front drive axle boots replaced and serviced - any possibility something wasn't reassembled correctly on the front differential?
my mechanic thinks that the issue is the filter isn't allowing enough transmission fluid to flow under full load. A transmission fluid change and new filter ought to take care of this then?
Or is the damned transmission about to grenade? It's basically stock, 110k miles, with a Level 10 valve body and MTM reflashed TCU. I haven't done any 100% throttle pulls since getting my car back, for fear of whatever it is that changes gears (I know jack shit about slushboxes) will break. Would this be the torque converter?
None of the gears seem bad - I put it into manual and did pulls in all five gears. Same thing - subtle vibration.
btw the mechanic said that one doesn't just change the transmission fluid and filter. You have to set two different parameters (with I'm guessing the TCU) to tell the car about the viscosity of the new fluid. Failure to do this is a sure route to destroying the transmission. True/false?
I'm planning to sell my car soon and want everything mechanically sound with no ticking time bombs, at least within my control. May not make the most sense to spend a few grand on a car I'm selling, but my passion for motor vehicles has never made financial sense nor been rational. It's also in a sense paying it forward - the guy who sold me this car was about the most OCD car nut I've ever met, and it showed with the physical and mechanical condition of the car. Since I'm not in an urgent selling position, my plan is to accept an offer only from a true hardcore VW/Audi enthusiast.
