check engine light and I can see it shift into different gears. Just doesn't move. I will check the fluid. Also the car moves a little after it had been sitting for 20-30 minutes

hey u still with me ?

Customer: replied 10 months ago.
Hey Sir, the fluid is okay. Forgot to mention that there was a humming sound a few days before and it was more noticeable when the car broke down. It moves a little but when you increase RPMs very high. Also, it won't go backwards, even when you put it in reverse.

Expert:  Chad Farhat replied 10 months ago.

HOW MANY MILES ON VEHICLE ? AND HAVE U DONE AND TRSN SERVICE , LIKE FILETR & FLUID CHANGE ? IF U CAN TELL ME ?

Expert:  Chad Farhat replied 10 months ago.

FIRST ,1- SCANING RETIEVING TCM CODES (TRANS CODES WIL BE IDEAL , I BET SOME WILL BE THERE INDICATING TRANS FAULT) TO CONFIRM WHAT WE HAVE , GRINDING NOISE ARE NOT GOOD ,USUALY INTERNAT)

2- YOU CAN ALWAYS TRY , FRESH TRAN OIL & FILTER

3- IT IS ACTING LIKE A FAILED TRANSMISSION , SO BEST THING TAKE IT HAVE IT CHECKED , AND HAVE IT REBUILD , NOW DAYS ,U CAN DO IT AROUND 1300 WITH WARRANTY

IF U GET THE CODES LET ME KNOW , I WILL TELL YOU WHAT THE ARE

A 5 STAR POSITIVE RATING IS MUCH APRECIATTED.

THE POST WILL STAY OPEN FOR YOU TO ASK ME FOLLOW UP QUESTIONS ON THIS MATTER EVEN AFTER YOU RATE ME .

THANK YOU & GOOD LUCK. LET ME KNOW IF U NEED ANYTHING ELSE .
