Hello and welcome to JustAnswer!

Codes 21 and 22 from the ABS module are for each of the front wheel speed sensors. These may be set because of wiring issues or a failure of the sensors themselves, the sensors are most common.

25 and 26 don't show to be valid. Can you double check these?

Customer: replied 1 year ago.
Those are the codes that flashed on anti lock light. Indicator light does not illuminate when placed in drive. At 65mph rpm is 2800.

What about the rpm at 65
Expert:  sprinkles08 replied 1 year ago.
Uf you feel it shift four times then it is shifting correctly,but the torque converter clutch isn't locking up at the time the P0740 is active.

Do you feel it is the solenoid
Expert:  sprinkles08 replied 1 year ago.
the most likely cause for the P0740 is the solenoid.

Is it going to hurt the tranny without OD
Expert:  sprinkles08 replied 1 year ago.
You have overdrive if it shifts three times from a stop.
