My friend has a 94 Accord LX. The car was driving fine a few days ago than all of a sudden, on the highway, the car shifts down to 3rd gear, while the car is in D4. I drove the car around for a little bit and I notice that it runs only in 2nd and 3rd gears even while on D4.

The transmission module is fine and I don't know where to go from here. Please Help!

 

It's sounds like a tcm to me.But is it hard to get out of park,If it is it could just be a bad shift cable.

 

check your shift solenoids

 

going from park to reverse and neutral is fine, just driving gears have problems. Occassionally the car will kick into 4th gear but it's usually just for a minute or two.

Pardon the ignorance but how to I check the solenoids
