Accord 3.0l Transmission Help...
 

Ok, my Transmission Stopped shifting this week and will only run in 1 gear. No Reverse and D1-4 run the same. Code P1751 & Flashing D4 which I know points towards the Solenoids but could the transmission be going out?
Also, The fluid on the Stick Looks and Smells ok. Didn't know if a Drain & Fill with newer solenoids would correct the issue. Also, I drove it around the block earlier in all Gears & All gears are the same, cleared code and comes back almost immediately even when parked. No changed in gears except in P D4 or N.
Any help much appreciated

This is the type of issue which is virtually impossible to diagnose over the internet. The fact is, the 4-Speed unit in your car is not known for longevity, and with 195,000 miles on it, there probably isn't much life left in the tranny.
