The most common whining noise from that tranny is the transmission pump. Sometimes they have a high pitch whine noise yet nothing wrong its normal. Sometimes its an indication of the pump being over-worked due to a dirty filter or fluid low. Turn engine on and check tranny fluid level. If low add to cold mark on dipstick, check for leaks under vehicle. If fluid appears very black or burnt smell, recommend flushing fluid and replacing filter (located inside tranny pan) yours will be a 4L60E type tranny.

My 2002 Chevy Malibu sometimes shifts very slow. I will go from park to drive and there is about a 3 second delay.


I would first check the fluid level. If it is a little low it could cause the slow shift. I would also recommend putting in a can of TRANS X. It will clean up the valves inside of the tranny. I did this with my 2001 malibu and never had trouble again. I have 290,000 miles on it!

It doesn't sound like a solenoid, check the universals and if it's not those, it is more than likely a linkage problem,

Trans prob


You can NOT check ATF when the engine is off. It must be running. If the ATF is dark, brown, or smells burned, then you need to change it, but it is probably too late. When you turn the engine off, the fluid in the torque converter drains back and gives a reading much higher than real.

The speedometer on my 2002 Montana stopped working and it started to shift irregularly. It doesn't shift at the right time and lurches the van when it does shift.


the trans is not getting a speed signal, fix the speedometer, that will also fix the trans. check the speed sensor first. the service eng soon light should be on.

Grinding in and out of 4 wheel drive


You say 'new' truck, 09? or new used? I have had 3 Fords, 3 w/ manual trans. case, if you go into 4x4 Low range, you must come to a complete stop before shifting the trans. case to 4x4 mode, and I always put trans (automatic) in neutral before slipping into 4x4, it engages smoothly, no grinding. 4x4 high range can be put in while moving, but I would let off the gas pedal, shift to 4x4 high range, then resume accelerating. If there is any grinding going on doing it as above, something isn't right. Check the trans. case fluid level also, to make sure that's not an issue.

2000 Chevy Prizm Lsi 4-speed auto trans. problems


That does sound like a linkage adjustment problem.

If that does not work, I'd try a fluid change and filter. But your diagnostics with pulling on the gear shifter is a pretty good indication of a linkage problem.
