Driving the other day and my tranny skipped and then the blinking D4 light came on. I had the codes run and it said it was the lock up shift solenoid B. I purchased and replaced it. It worked for one trip to town and the light went off, and now it is messed up again and the D4 light is back on, I then tried to flush the tranny fluid but the problem continues. Please help I've already spent too much on this thing.

 

Have the codes pulled and post them here. Not the description, the actual code P07XX or P17XX.

 

P1773
P1491
