After I drive my van for a period of 30-45 minutes on the highway, I begin to hear a high-pitched whining noise. It gets louder as I accelerate and remains even after I am parked. After slow driving for about another 30 minutes, the noise goes away.

I took it to the transmission shop and they replaced the torque converter, but the noise did not go away.

I read that it might coming from the power steering pump when the fluid gets hot.

If anyone had this problem, or know what it might be, please let me know. I wasted $2200 on the torque converter and don't want to waste any more.

Thanks,
Scott

It sounds like the transmission shop missed it because the front pump is sucking in air so it could have bad seals or the filter is clogged causing the issue did they check that?

Thanks for the answer. The whining continues when placed in Park with the engine on.

I will take the van to the mechanic to a different mechanic.

There is seems to be a miss but Goodyear says it is the tranny. There was also a whine and they serviced the tranny and it went away. Are there prob?

2001 Chrysler 3.3L automatic T&C revs up but gears on tranny are slipping, whining sound. Lucas additive added to tranny. Car barely moves and only after reving engine for a while. It shifts smoothy.

Can you clarify how it can shift smoothly if it's barely moving? Has anyone checked the Transmission Computer for stored diagnostic fault codes?
