Acceleration hesitation first 10min. when engine is cool

[BlackVX]

132K on my 2001 and no transmission issues...Why does he think the transmission is going away just based on dirty fluid...have you had any problems?

Well, there is an issue with the VX jerking for the first 5 minutes when the engine is cold. My mechanic is still trying to figure out the issue at this moment. The fact that the fluid is still really dirty within one month tells him that the transmission might be going away (I drove less than 1k mile during the 2 transmission fluid services).

Thanks,
Michael

I can understand the BASIC conclusion of dirty fluid not sounding good. But, your mechanic doesn't sound like a trans expert either. There's a Certified shop near my house that's good. Maybe you have one in your city? Mostly, I'd seek out a specialist in transmissions. They aren't rare either...as our automatics were used in many vehicles.

I remember when my fluid was changed, they didn't dump ALL the fluid. It might have to do with the valves/solonoids getting "used to" (e.g., worn in) where they work better with the heavier/dirtier old fluid? I've heard this more than once -- where a transmission doesn't get it's fluid changed UNTIL it's finally many years old.

That said, I would think metal shavings (versus "dirt") would be an indication of failure. Can you trust the shop that changed the fluid? Maybe they did just as I described...and partially flushed it? If so, that might not be bad AND it might explain a return to "contaminated" color. I still vote for the possibility of you having a problem with that sensor board on the side of the transmission.
