I have never really worked on automatic transmissions so I'm not that knowledgeable I am wondering my car won't drive when I jack it up off the ground the wheels turn and will accelerate when giving gas code given was for transmission speed sensor I am basically wondering what I should do I have a number of thoughts and have ideas to try wondering what order I should do or if it's not worth doing anything because the internal parts are worn could that indicate the clutch plate or some type of internal parts being worn out I plan to drain and fill... also I was going to clean and check/ replace solenoids. I have heard there may also be a problem with the linkage cable being loose causing it not to engage fully/correctly? Really wondering your thoughts on order of operations... in this case would a transmission flush or running some type of pressure through the system possibly help? or whether or not it indicates worn internal parts?
Thanks so much,
