having some auto problems its a 89 turbo 7mgte
Driving around town low speed in drive she drives just fine. However when i hammer it she still shift at 3-4 thousand rpms. Then i'll put her in power mode and she go 3,500-5,000 before shifting. but when i put her in low she does not stay in low she shifts out like she was in 2nd and she'll stay in 2nd but she will allmost never shift into first. i checked the fuild level and it was about a little low toped it off and it drove better for a while and now it is back to its old self.
