my 99 sport isnt going into or staying in overdrive. it just started doing this yesterday ive had no other problems with the trans. i checked the fluid level and it was a little low so i added too it. drove it again and it still does it. if i take it out of drive and down to 3rd then back up to drive it will go into overdrive usually. im at a loss so i need some advice on this one lol

 

Almost sounds like the TCM or end clutches are going bad.

 

any check engine light?

if so, get it checked. if it shows a throttle position sensor issue, then that is likely the cause of your issues.

if the tps is reading "low voltage input" on the scanner, you could have a bad alternator...just had that happen. was causing throttle position, running, and shifting issues...while still charging the system at 1.2v rather than 12v.

 

He's alive?

 

yeah. been busy. brother's medical issues, work, fixing things at home, repeat. don't know where sleep fits in there, but it does...somehow.
