Transmission Problem P0700
My Honda Accord 2002 2.3lt V4 started with transmission problems a little over a year ago. When cold, the card would hard shift into 2 & 3rd. After a while, say 5 minutes of driving and changing gear all gears changed fine.
Initially I took it to a technician who ended up putting in a new master rebuild kit. When the car left the shop it still had the same problem just changes weren’t as hard as they used to be. I ended up taking it to the trany shop 3 more times over the following 3 months with no positive results. I continued to drive the car this way, and I would let the car warm up 10 minutes before I left and this seemed to help for a while. As time progressed the symptoms got a little worse. The reverse started to shift hard also, and every once and a while (usually when I didn’t warm up the car long enough) the hard shifting would make D4 start flashing and the gears wouldn’t engage and I would have to turn of the car, change to Park, turn on the car and back to D4.
So finally I decided to take it to another trany shop. They scanned the car and the following code came up:
P0700 FAULT IN TRANSMISSION CONTROL MODULE
P0739 3RD PRESSURE SWITCH
P0780 SWITCH MALFUNCTION
P1751 MECHANICAL FAUL IN HYDRAULIC SYSTEM
They said that the gears were burnt and that they had to put in another master rebuild kit and that the torque converter also had to be rebuilt. They went ahead and made the recommended repairs. After they completed the repairs the said that the car was still having the same issues as when I took it in. And it is still giving a P0700 error code (I asked if there were any other codes along with this one and they said the P0700 was the only error code). They said they swapped the solenoids a few other parts to see if that was the issue and that the car continued to present the same symptoms. They deduced that the computer was bad and that it had to be replaced. This is where I am at right now. I have a feel the once the computer is repairs I am still going to be left with the same problem.
Can anyone make any recommendations? A new computer is going to cost a fortune as it has to be programmed by a Honda dealer. I've looked online for something affordable but it always boils down to have to reprogram the computer at a dealer.
I am aware of the lawsuit and all considerations that Honda has given its car owners. But my car is out of warranty and it has 168K miles already. My transmission was repaired by Honda for similar issues at about 70k miles (I purchased the car at a Honda used car lot, so the engine and trany were cover under a 100k Honda certified vehicle warranty). Excuse all the incorrect terminology.

Re: Transmission Problem P0700
Some problems I've noticed with my 2002 Accord 2.3L 4cyl... 1st personal-The tranny started messing up? around 75k. Like it would stay in a gear for a second after it changed gears...? Whatever, warranty covered it. 2nd. I think that was under warranty too. Idle control Valve (ICV) would run at a low rpm and be struggling sometimes when stopped to that it'd almost shut the engine off, that only happened once tho and I think in my garage cuz I was revin it to see. I'm now at 121,000k and it's been doing it every now and then but its not a problem, doesnt mess with the driving and it's rare. So whatever. So that's a recurring problem for MY Accord.
Now on many Accords MANY on 2002 I see water has gotten into the read break lights, including mine, no technical problems with it but cosmetic (for now), the water takes off the silver paint in the rear brake light box...Can't really notice unless you look. We'd notice. Lol. Thats not been recalled and so many have that problem, strange.
Oh yeah, an Airbag recall I think it twas in 2010, if not 2010 def. 2009. They took care of that well. As with the tranny. Gas isn't good for a 4cyl 2.3L!! 23 Hwy/St. 30 Hwy. I never drive just street si I dunno bout that, I live in Los Angeles. I actually think it's too big of a car for such a small engine, it feels heavy unless it's in D3,lol. If they wanted to do a V4 at least put a bigger engine, I dunno. At least 2.5!! Just wanted to inform ppl because I see ppl posting regarding these things, so yes they happen.
