Transmission problem
1999 Honda Accord 6 cyl Front Wheel Drive Automatic 154 k miles

With my b7xa tranny, I have noticed it is shifting pretty hard from 1st to 2nd gear. I changed the tranny fluid 2x with dexron 3. Its not as sudden now but delays and then lunges into gear now.

Its shift a little better, not so hard, but it has a real delay before it kicks into 2nd gear. A local tranny shop said that it might need a soft overhall. But I wanted to know if you had an idea for what part cld be going bad or if you had heard about this problem before? Pls let me knw as I wld love to hear your thoughts on this specific issue. Thanks bud

Can you let me know if you get any answers on this specific problem? I wld love to knw the exact part that I cld replace instead of doing a complete overhall. Thanks

Hi there,

You could first run a scan and check for any unresolved fault codes, short of this you really need to have the transmission line pressure checked and then have a visual inspection of valve body and servos as this could be a low pressure problem or sticking shift valves, all unknown until it is sighted first hand.

Is there a scan that can be done, specifically for the tranny? Its not just a code reader? That cld be a good place to start, although if it is justa code reader, than there is no check engine light on so it wldnt pick up anything. Let me knw thx buddy.

Hi there,

Not all set fault code will trigger a check light, so get the scan done as you may have a fault code in the system.

I had the trans scan done and there was no codes found. I have seen a post on your site from terryl00 about the same exact problem that I'm having. He has the same car, 98 accord v6 3.0 and same problem. He said that his gear 1st slips and bangs into 2nd almost exclusively when its cold, but when it warms up, like mine, shifts much better and easier. You guys suggested he replace the A/T clutch pressure control solenoid.

Please take the time to look at your website's link to his question. I think it would help diagnose the problem...

Please let me know if changing this solenoid would help for this same problem cuz I don't see a conclusion/final post from him stating if the solenoid replacement resolved the shifting problem or not. Pls let me know what u think

Well today I had the hydraulic system check and tested. They said that there were no abnormalties detected. Also checked the vacuum lines and solenoids, and they all seemed normal with the correct voltage. I dont know what the next would be to get checked or do, but I wld appreciate it someone could give me a hint here.

The Trans shop said that they wld change all solenoids for $925 with no guarantee or $2500-$3000 for a new tranny with guarantee. I dont know what to do next. Any advice.

Still no fault codes, no engine light on or anything yet.
