trnsmission problem

[giorgio959]

hi,
can somebody tell me why when push on gas and rpm get's over 2000 the tranny it's starting to crying
at any gears

What is the fluid level? What is the fluid condition? Is there evidence of air entrained in the fluid when it is checked with the engine running (standard procedure)?

Does the transmission shift through the ranges automatically? Does it shift through the ranges firmly if operated manually?

Is there any similar noise when revving the engine to 2,000 RPM while in Park?

Was there evidence of metal in the transmission oil when it was drained, or only friction material?

Since the noise occurs at 2000 engine RPM with the vehicle moving it could be a few things in the transmission or it could be the engine or the accessories like the alternator, PS pump or water pump. Just to be certain the noise is not due to an external accessory it may be helpful to remove the accessory belt and start the engine to test it again.

About the only thing moving in the trans when in Park is the torque converter, pump, and drive chain and sprockets. If the fluid is not foaming the pump may not be the issue. There was a TSB (0-07-30-007A) regarding the chain, sprockets, and sprocket support bearings on the transmission, and that may be the cause. There is no good repair for this issue short of removal and replacement of the chain and sprockets. Transmission oil additives will not improve this. If the trans is removed for repair it would only make sense that new clutches and steels would be installed (complete rebuild). A used transmission is likely to have similar symptoms unless it is rebuilt to replace worn parts.

Hi giorgio959 !
Most likely you may have a pressure control solenoid going out, which would explain the hard shifts and whine. Best to check the computer for any codes relating to the trans.
Good luck to you!!!
... I would like to complement the - if I recall correctly, this tsb indicates that there may be dirt in the valve, causing the condition. If this is the case, similar dirt may also be in the valve body. You should clean or replace the valve body .
