Hey everybody, I bought a 99 CR-V as a commuter, looks like this car was kicking up engine code 740 and the guy reset the engine light right before I spent my last dollar on it. It sucks, and now I'm stuck with it. Bought a TCC solenoid from Napa based on year/make/model, bolt patterns don't match. Apparently this con artist wasn't lying when he said the trans had been replaced. This "replaced" tranny has the code "B20B" written on it, which I gather is a type of JDM transmission. How do I find the correct TCC solenoid, or the part number of the transmission that will lead me to it. Any help is greatly appreciated, it would be great to know if swapping this part will save me from a replacement/rebuild.

Sincerely,
A sucker who's stuck with a lemon

 

P0740 doesn't mean the solenoid is bad. It means there is something wrong with the torque converter lockup circuit. Probably a junk transmission. The 4 speed auto behind the B series is a pile of trash and has been from day one.

 

Fair enough, but if I was going to try replacing it as a hail mary pass, how would I find the right part?

Also, is there a transmission you would recommend if I do bight the bullet and swap it out?

Thanks for your response

 

A 5 speed manual.

There is only that junk 4 speed automatic to bolt in. Nothing else will fit. They were all more or less the same pile of junk be it Integra, CR-V, Odyssey, or Accord.

B20B is your engine code. Not sure how to identify a Honda automatic but here is a list of possible transmission models.

I wouldn't waste your money on a solenoid unless you find one for free. Usually it is the filter in the tranny that packs up with clutch fiber and starves the whole system of fluid and quickly turns into runaway meltdown. The first signs are the circuit codes. Circuit is not getting the required oil flow to operate.

 

Thank you for the info, I really appreciate it. It's a bummer honda thought a non-serviceable filter was a good idea. I'll marinate on swapping for a manual 5 speed and try a few drain and fills while I figure this out. With any luck the transmission gods will dislodge the funk in that filter but I'm not holding my breath. Thanks again.
