Automatic transmission slips. Repaired once but after 500 miles slips again.
While I am driving on "D", it goes to "nutreal" or blocks on one gear. I stop the engine and start again it goes normal for a while and then having the same problem. An other symptom is; while it goes normal on "D" if I push the gas pedal for a lower gear it makes a strange noise, then, after 1-2 seconds it goes to lower gear!
I changed ALL mechanical parts; gear set, gaskets, sensors, filter, etc.., however, after 500 miles it slips again! Could it be an electrical problem?
Please help. I need any kind of suggestion.
97.000 miles.
Well cared.
Fluid level and brand is ok.

yboy82 4/26/2011It could be electrical, if the fault of your vehicle's proble is stuck/damaged main control solenoid. If possible verify if there is a stored trouble code in your PCM. -
Spoon Sports 4/26/2011It can be because of automatic transmission bands, which are rubberized bands linking together the gears within an automatic transmission, are vital to transmission gear shifting and operation. Worn or broken transmission bands can disrupt automatic transmission gear function and allow gears to slip out of place.
Vacuum pressure, supplied directly from a vehicle's running engine, plays a large part in automatic transmission function. Vacuum pressure helps to keep automatic transmission fluid moving and under set pressure guidelines; any disruption of vacuum pressure to an automatic transmission can cause a variety of transmission problems, including transmission gear slippage.
An automatic transmission torque converter, which is a high-powered hydraulic pump responsible for pressurizing automatic transmission fluid, can cause a transmission to slip if it loses its ability to generate enough force to properly pressurize transmission fluid.
