i have a 2000 honda crv with a transmission code p0740 indicates faulty lock up control systemtech said it either could be the lock up solenoid or internal transmission problem .here is what happen when starting the car and still cold for the past week trying to engage the car dosn‘t wonna move then it goes ok yesterday while going up the hill the car decided that it dosn‘t wonna go over 20 mph so i took it to the mecanic and they pulled out the code p0740 and they said it could be the lock up solenoid or transmission problem the truck have 121000 miles on it so any sugestion on what to do cause i never had a slipping in transmission or anything like that so please help

RE: 2000 honda crv transmission problem? i have a 2000 honda crv with a transmission code p0740 indicates faulty lock up control system tech said it either could be the lock up solenoid or internal transmission problem . here is what happen when starting the car and still cold for the past week trying to engage the car dosn't wonna.
The P0740 code is set when the transmission torque converter clutch is not engaged when it should be. Basically, the torque converter clutch is a mechanical coupling inside the torque converter that reduces transmission slippage when the vehicle is going over approximately 40 mph. the way the converter clutch is applied is through fluid pressure inside the transmission. when a torque converter clutch fails to apply there is a problem with the pressure circuit inside the transmission. That problem can either be that 1) the solenoid that controls the fluid flow through the passage isn't working or 2) the fluid passage is blocked so that no fluid flows through it or 3) the transmission is low on fluid so that there isn't enough hydraulic pressure to operate the converter clutch control. I assume that the level and quality of the transmission fluid has already been checked. The first question is when was the last time the fluid was changed?. there is a good chance that the passage for the fluid is restricted by an accumulation of debris due to 121,000 miles of wear on the internal transmission parts. I would strongly suggest that you start by having the transmission flushed. Honda doesn't recommend that the transmissions be flushed but if you have a problem with blockage or restriced fluid flow then that's the only way that I know of to clear it. if you still have the problem after a flush, then have a pressure test done on the transmission. That will tell a technician if there are any internal problems. as for the P0740 code, that should cause the check engine light to come on. if that warning light has not come on then the code could be an intermittant one. As a rule, the CRV transmissions are extremely reliable and internal failures are uncommon. That doesn't mean they don't occur, but the odds are in your favor that its not something major. hope that helps
