Obd11 p0750, p0770

[GTCelica]

I am sorry. Hello to everyone out there. Never did anything like this before. Also Just to let everyone know this is my first Toyota. Would greatly appreciate any help or ideas on how to solve my problem.

I just purchased a 2000 Celica GT with 195,456 miles on it and as far as i can tell and research all service was done to this vehicle except tranny fluids and filter. Now I am showing two codes P0750 and P0770 and it does not shift into overdrive and sometimes not even drive. Any ideas anyone.

Both of those codes are for shift solenoids in the transmission. I'd take it to a transmission shop and have them look at it.
