Default The dreaded V6 tranny problem

I got a 98 V6 accord i just hit a little over 212k miles and my tranny gave out. anybody have an idea of what could be happening

1st gear jumps and will jerk the car pretty hard feeling like im reving the car while putting it in gear

2nd gear is about the only gear that works fairly well but slips real bad putting into and taking out of gear

3rd gear will jerk real hard kind of feels like it is slamming the brakes then letting off but coming from the tranny

4th gear is just not there lol it feels like the torque converter wont lock up and the engine revs freely

Now the real question is will i need the tranny rebuilt, if so would it be worth just to swap it to a 6speed standard tranny, as I have been reading the B7XA tranny is pretty much garbage

The B7XA is a good design, although some of the machine tolerances and valves are suspect. With good aftermarket correction kits it will shift amazingly fast and smooth. On the scale of the worst transmission designs I have rebuilt, the B7 lineup would be a 3 out of ten, ten being the worst. This factors in cost of repairs, availability of parts, and initial longevity. The 98 model did have a rougher patch because it was the first iteration, but I have seen many 00-02 V6 Accords with over 180,000 miles with little shift lag.

Any DTC's?

Since it seems every gear is affected, you probably have a blocked up filter causing a loss of hydraulic pressure. Run of the mill problem actually. 2nd gear is famous for premature wear due to a leaky clutch pressure control valve. A kit that updates these parts can be had for 100 bucks or so. Also verify your fluid level and type. What are you using? Have you ever maintained it?

The primary mode of failure is the converter overheating the oil, oil overheats the clutches, and the clutches shed, blocking up the oil filter and valve body screens. The damage in my experience is little more than an overhaul kit, converter, and shift kit to fix. It is not that hard to do yourself if you choose to.

The automatics are fairly consistent in wear and tear. A 6 speed is by virtue of the previous owner, could have been grenaded its whole life. Be prepared for that too. A 6 speed is not bullet proof either.

I appreciate it. I don't know for sure how it was maintained I just bought the car about 2-3k miles ago. I believe it was taken care of though as the rest of the car was taken care very well. So in your opinion would it just be better to get my current tranny rebuilt? I'm not familiar with transmissions so I don't know how I feel about doing it myself. Lol if so can you lead in the right direction as to where to find parts for a rebuild?

You can take a chance on a used one and hope it does not produce the same problems you have now.

The Transtar rebuild kit for your transmission, including all seals, gaskets, pistons, and o-rings costs about 240 dollars. A converter will run you between 120-200, depending on if you want a new one, or a rebuilt one. The Superior STL-388 shift correction kit can be had for about 100 bucks. Add about 100 dollars for fluid and misc stuff.

Most of the tools you'll need you can get from a parts store, including a torque wrench that measures down to 80 inch pounds. The only special tool you will need is a clutch return spring tool, which can be had for around 40 dollars.

Thanks for all the info I've been calling around to local shops and they want $2200-$2300 to rebuild it. Now I found a reman tranny on eBay for 1200. But I can also find another cheap Honda for around 1500. So now I don't even know which way to go. http://m.ebay.com/itm/171304760182?fits=Make%3AHonda%7CModel%3AAccord

What do you think?

Personally, I think you should educate yourself. I started my career after finding myself in you exact same shoes: A $2400 rebuild and a 2 week wait, niether of which worked for me. Owning a car is analogous to owning a house, the more you know about maintaining it, the more beer money you'll have. (Plus the fun of doing it yourself.)
