Condition
Some customers may comment that the Service Engine Soon (SES) indicator is illuminated and that while the light is illuminated, transmission shifts are extremely harsh.
Cause
These types of conditions may be caused by an intermittent connection at the transaxle 20-way connector to the wiring harness interface.
Correction
If a DTC was recorded and the Freeze Frame and Failure Records back it up, a problem existed at one time with the wiring and/or the connectors between the transaxle and the PCM. Therefore, a thorough inspection and/or repair of the wiring harness at the transaxle 20-way connector for one or more of the following conditions may be warranted.
The wiring harness is stretched too tightly or other components are pressing on the connector body itself causing a downward pressure on the connector body and possible intermittent contact of the wiring terminals. Ensure proper clearance to any other components and wiring (i.e. hoses, battery cables, etc.).
^The terminals are not fully seated into the cavity of the connector body.
^The male terminals in the transaxle portion of the connector may be in the wrong position (i.e. bent).
^The female terminals may be loose and are not making proper contact. Check the tension with the proper terminal tester from the GM Terminal Test Kit J 35616-A or J 35616-92. If the tension is low, replace the terminal. Do not try to re-form the terminal.
^The crimp of the terminal to the wire may not be satisfactory (i.e. loose, over insulation, etc.).
^The wiring connector is not properly seated and locked in position. Ensure proper seating of the connector into the transaxle and that the connector is properly locked in place.

It is a valid TSB but I've never seen where the solution works. Supposedly a lot of GM cars with 4T65E tranny came off of the assembly line with a loose 20 way connector plug to the tranny. Thats the big gray connector on the top of the driver's side of the tranny.

The TSB recommends disconnecting it, inspecting contacts and properly reconnecting. I've never heard of it correcting anyone's tranny problem but its worth a try.

I agree with you, but nobody cant find the problem. I have hard upshift.No ses light, no codes. Car have 85000, 2003, 3.4 eng. Last month oil and filter was changed.
Maybe i can use some kind of oil treatment for tranny. Mechanics saying treatment are chemical and can destroy rubber parts inside. Any ideas what it can be, or what i cand do to fix that. Overall was changed: Cat, fuel filter,air filter, sparks, wires.
Can it be fuel pump or fuel pressure regulator or o2sensors or what it could be. This car piss me off.
