P0740 hello all.....well my 1999 acura cl 2.3 engine light came on and its a p0740......well the tranny shifts good dont no what it could possibl mean and why it came on please help thank you all

P0740 is the torque converter malfunction code. The converter is in between the engine and transmission. The fluid that you are seeing is transmission fluid. It needs to go to a mechanic to narrow it down from there.

help Acura 3 2 TL 2001 P0740 Transmission MUST BE FIXED AcuraZine Acura...

This code is set when the transmission control module detects improper voltage at the torque converter clutch. This can be caused by low tranny fluid/dirty tranny fluid/defective torque converter clutch solenoid/electrical connections to from solenoid

On some cars, there is a TCC solenoid in the transmission which can be replaced by removing the bottom pan. In some cars this solenoid can't be accessed without major disassembly.

if it dont crank how would you say the starter is good.
you dont know that. sorry'
making assumptions is the top killer of all diagnosis.
you set in driver seat:
i key on, is the CEL ,charge and BRAKE lamps glowing
if not you lost all power ,12vdc to dash and ignition.
they must glow, if not the battery is drained or a fuse is blow.
check all fuses , now.
if all those normal lamps glow, (warnings) per the operator guide.
the good, you have 12v power.
proceed to cranking..
"as they say, Call the Auto Club time"
the first check, is called a jumper cable jump start off a running car.
if that works, then the starter is good and the battery was ONLY discharged. (no assumptions. see?)

then and only then could you say, starter is good. see?
if the car JUMP passes ,then battery bad or charge system failure....
(ask for help that topic, "my battery is drained, why?"
if the JUMP fails (to other cars battery)
we then hot wire the starter, does starter crank fast and robustly>>?
yes?, then the key line is bad.
no ?, then the starter is bad. or its 2 huge cables are bad.

YES?? starter hot wires good. then? !!!!
see the tricks here,
my guess is this car is A/T tranny, Automatic.

Shift Soleniods go bad i would get the part off ebay just b/c of price, and change the fluid in the tranny sounds like it is old use honda OEM trnny fluid only, it fix this problem on my cL, it will work for you.

try changing the tranny fluid new filter and see if this helps if not you may have to adjusts the bands on the tranny which you will have to pull tranny

That happened to me when my tranny went out. did it intermittently for two weeks when all of a sudden if felt like i was driving with one gear, then it wouldn't go anywhere. It failed on me @ 99,731 miles. so it was covered under warranty. Good luck.

firstly, there should be a small vertical slot next to the shifter labelled "shift lock". Stick your ignition key in there and jiggle it while you try to depress the shifter button. That should get you out of 'park'. Now, when you say a brake lamp is on, do you mean on the dashboard or one of the actual brake lamps?

The Transmission is likely shot. That year along with others had transmission defects. My new 2002 TLs died at 21k miles. I go to Acura for most all service and they gave me a $1500 discount on a tranny. It still cost me $3500.
