Auto transmission problem

[Smacca86]

Hi guys,

Car travels about 55km's at 100kp/h before it drops back to 3rd and remains there and doesn't gear up to 4th again.


Any ideas as to why this would happen?

Cheers,

Jarrad

service it. clean MAF, clean TPS.

first off get it serviced...


if problem persists id say up for another trans.. i had this problem and solved it by replacing the trans..

because its tired it slips and overheats in overdrive, heat override drops overdrive..
