question for the REAL honda techs
and by REAL, i mean someone who's a tech at a honda dealership or has access to the same information...
i've got a mil/cel with 2 codes... p0700 and p0740... lock up control circuit if i remembered correctly. comes on whenever i drive at a steady 55mph +/- 5mph for 1 minute.
i've read somewhere that there is a TSB for these two codes that comes on after replacing a transmission, however, i do not have access to honda's TSBs and do not know what the cause and fix is.
can someone look up (or have first hand experience with this) please give me some insight on the fix to this problem? thanks

Re: question for the REAL honda techs (taz77)
Have you cleared the codes yet?? If the light comes back on after they have been cleared with a scanner replace the transmission. I've got 2 SOHC VTEC transmission at the shop and can make you a smoking deal.
The diagnosis says the codes you have are Auto Transmission Related and should throught a mil#70. The Honda A/T transmissions are easier to replace than rebuild!

cleard the codes, but comes on at 55 mph when at that speed for more than 1 minute. it's really no big deal right now, cause all i really have to do is drive over 60 mph and it'll never come on. i just want to see if it's an easy fix if it'll help increase my fuel economy.

There are no bulletins specific to that model for a p0740. A damaged o-ring on the snout of the torque converter is the most likely cause. Has the transmission been out of the car recently? I would probably live with it if it was mine.

ok... i found the tsb (nhtsa# 10009028), but that's the same thing i saw... no explainations on what the cause of the p0740 was and why it came on after an r+r of the transmission. it also doesn't show info on what the fix is.

That's not a tsb, it's a service news article. It basicly says you f-ed up the converter o-ring.

is that what this is... ok.
well, i've had the car 5 years now... i bought the car used with 38k miles on it so just outta warranty. unless there was something wrong with the transmission with the original owner, i doubt it was replaced. it really wasn't until a couple years ago that the light came on, and i haven't had the transmission removed. it's probably not come on prior to that cause i've always droved over 55mph, and recently, i've had the urge to just cruise cause i'm in no hurry anymore. i guess i'll just have to live with 65mph instead.

A/T DTC P0740 Repair Tips
On all Honda models with A/T, except Passports,
if you’re doing a repair for A/T DTC P0740 (lockup
control system), refer to this table first:
If there’s no service bulletin for the vehicle you’re
working on, go to the DTC P0740 troubleshooting
procedure in the appropriate S/M. If the
troubleshooting procedure recommends
replacing the A/T, make sure you have a reman
A/T on hand. Remove the original A/T, and look
at the condition of the torque converter O-ring.
Then, follow these tips to ensure a lasting repair:
Missing or cut O-ring. If the O-ring is missing or
cut, internal leakage of ATF can cause DTC P0740
to set. Replace the O-ring, and reuse the original
A/T. Make sure the problem has been resolved by
connecting your PGM Tester and test-driving the
vehicle using the previous P0740 freeze data
parameters (match the TPS and VSS values for at
least 25 seconds). If the DTC comes back, install
the reman A/T. If the DTC doesn’t come back,
return the original A/T for warranty claim.
Flattened or deformed O-ring. If the O-ring is
flattened or deformed, replace the A/T. The
O-ring can get damaged if the ATF pump seizes
up and overheats. Install the reman A/T. Make
sure the problem has been resolved by
connecting your PGM Tester and test-driving the
vehicle using the previous P0740 freeze data
parameters (match the TPS and VSS values for at
least 25 seconds).
O-Ring is OK. If the O-ring is round and in good
condition, DTC P0740 was most likely caused by
the A/T, the torque converter, or both. Install the
reman A/T. Make sure the problem has been
resolved by connecting your PGM Tester and testdriving
the vehicle using the previous P0740
freeze data parameters (match the TPS and VSS
values for at least 25 seconds).
Before you install the reman A/T, make sure the
O-ring on the torque converter is properly
installed.
hope this helps...your gonna have to get your hands alittle dirty though
