Goodluck! , your car has a hydraulic clutch so there is no adjustment check the fluid level you may just need to add some fluid , First I would try resetting the ECU by disconnecting the battery for a few minutes. This will remove the code. Then see if it comes back. Mind you you will not pass inspection, because the ECU will need to monitor a certain amount of driving "cycles" before inspection will accept the findings. Before that, replace your O2 sensors, and get those out of the way. P0770 is a Shift Solenoid E Malfunction. You will have to look at a manual to find out which Shift Solenoid that "E" refers to and where it is located. TC lockup, refers to the TC lockup solenoid. If so I would try replacing that and going from there. The auto transmission is a pretty complicated beast, and even the most experienced DIY'ers would go past the normal maintenance. HOWEVER, changing solenoids is considered, at least to me, DIY maintenance. Whats is your RPM when cruising at say 60 mph. If its more than 2400 rpms, then i would say it is your lockup solenoid. hope this helps , last time i heard of something like that someone stole the driveshaft. in any case you'll have to get a look underneath, , You have this posted in the wrong category.
