Hello, I keep getting p0700 and p0740 there is nothing wrong with the transmission at all. I believe somthing is setting it off. The fluid is fresh. I pulled the freeze data and got


coolant temperature 190 degrees
throttle position 16.8%
engnie rpm 2179
load value 56.8%
map sensor 58kpa
intake air temp 102 degrees

is there anything that looks wrong with this I cant figure this code out.

Thats all at 52mph

P0700 indicates that there is a fault with the transmission control system.

P0740 is a fault with the lock-up system and under normal circumstances you would not see any difference in shifting qualities.

The lock-up only affects the few hundred rpm difference when it engages or is not engaged. You would have some fuel consumption increase, other then that you would not note any difference.
