98 CL transmission problems

I have an 1998 CL automatic, I bought the car about 2 weeks ago, before I bought it I scanned it and no codes popped up only P1491 (EGR valve). When I bought the car the guy told me I needed to get a new shift solenoid. At the time it would shift a little funny into 2nd gear once and awhile. 1 week later it started to rev up real high in 2nd gear then bang into 3rd. When I slow down is the bigger problem. It bangs real hard into 2nd. My buddy told me he thinks that if I flush my fluid and change the transmission filter he thinks it should help. I scanned it for codes today and I got :

P1739 manf. control transmission / automatic transaxle

P0740 TCC circuit malfunction / torque convertor clutch circuit malfunction

P0730 gear ratio incorrect

Not sure what to do? I don't have a lot of funds so if someone could please reply I'd appreciate the help! I really like the car

your friend is right, flush the fluid but you should only use genuine honda atf. this transmission is quite sensitive. the best bet is to use honda atf. they are about 9 bucks a quart and you need 3 quarts to do a drain and refill. for a complete flush, which a lot of people don't recommend, uses about 9, i think.

after you change your fluid, reset the ecu and see if the codes come back. but looking at these codes, it does not look good. sorry

Only thing I would add is to visually inspect the shift solenoids and see how dirty they are.
