I'm beginning to suspect China or Russia has "Bots" on our Forum...
I can Accept, and Welcome people that may not have "that good of English' skills, and will try to help...
but now, I'm starting to get Suspect...
No complete sentances, no correct language, no correct punctuation, the info provided doesnt line up....

Kinda ruins this whole thing.

Well, too bad those IA-learning bots can't provide some tranny basics:

1) Ensure electrical connections at the tranny and Trans module/fuses ...and battery-to-body/engine grounds are good
2) Ensure linkages/cables are in good condition, and shifter 'feels good' clicking through it's gear select range
3) Ensure fluid is not dark or burnt smelling (if so, replace ...with new filter), and level is correct
4) Ensure no engine computer codes are present.
5) Replace any external solenoids or vacuum modulators (if present)
6) Last solution is a can of miracle trans medic in a bottle (that stuff does sometimes work ..if not short term) LOL.

Thanks for your help, I'm going to check the connectors, these days I changed the battery terminals, the oil is very clean, where is the trans module located?

Maybe non-native language, someone dictating to their phones, or they talk and write in run-on sentences. No big deal, we're here to help.

If the problem is upshifting too fast, the usual culprit is the throttle position sensor (TPS). If not, please describe it better.
I recommend testing the TPS with a meter to confirm the problem before replacing it with a Chinese made after market one.

Engine not running, key on:
- Measure resistance between the black wire to the battery negative terminal. It should be less than an ohm. If not, you might need to clean the grounds on the engine block by the dipstick.
- Measure the voltage between the battery ground to the other two wires. One will be steady, around 5-volts. The other should change smoothly from less that a volt to over 4 volts as you slowly open the throttle by hand.
