Yes, if they are bad or even one of them is bad, it will not shift properly.

SOURCE: torque converter solenoid stuck off DTC

There is a solenoid switch that locks up your torque converter to get a 1:1 input for your transmission. This solenoid (or less likely its circuit) does not operate. You probably don't feel the difference in driveability but this definitely affects fuel mileage of the car... The solenoid for your particular application is available for about 60$ Canadian at NAPA auto parts here in Canada. Not too sure about USD$ and labour costs...

SOURCE: 4L60E won't shift to 3rd on 1995 Chevy Astro 2wd

do the pin point tests, these start witjh running a trouble code test, autozone and kragen will do this for free, if u haven't had the trans apart then cross out any crossed wiring issues, but I do think you will find a problem with the 2-3 shift solenoid, either the solenoid has failed or the connector has a problem on the outside of the trans.

SOURCE: I need the torque specs and sequence on a 1998 chevy 350 vortec

Vortecs are a little different that old school small blocks, grab a Haynes or Chiltons, the cross patterns and specs are simply diagramed. Vortec, as any really, start with 25# then 45# and then final torque which I believe is around 70-75# but to be sure verify with the manual. AutoZones, Murry's, Adavance auto all carry the books, Cheap insurance.

1998 jeep grand cherokee 4x4. have the p0740 code. have to start from neutral, then shifts faily well. May start fluttering and making noise, have to put back to N, then to D and once again will shift. ...


P0740 JEEP - Torque Converter Clutch Circuit
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
- Vehicle may not shift into the highest gear

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted

When is the code detected?
Torque Converter Clutch (TCC) unlocked for 10 sec., ECM commands converter lock-up and did not record engine speed drop.

P0740 JEEP Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

Hi and welcome to FixYa!

Looks like that the problem will be on the torque converter. If the torque converter is faulty the gear tends to slip. I strongly suggest that you replace the transmission fluid and torque converter to resolve the problem. Once replaced a smooth ride and shifting will be noticeable.

Hope this helps and thank you for using FixYa! Have a good one!

My shifting is skipping gears in my 1993 dodge ram 250 conversion van. My mechanic doesn't know why. I think it might be something that connects to the transmission. donna_rdly@yahoo.com


First thing you will need to do is change the transmission fluid and filter. You may have metal shavings inside your transmission pan blocking the filter kit and this would cause your vehicle to skip gears. Try installing the new fluid and filter kit first. Since you will have the pan off, replace the A and B shift solenoid if the new filter kit and fluid don't stop your transmission from skipping gears

Hi, I have a 1998 Chevy 3/4 ton 4x4, automatic transmission, has had problems for quite awhile shifting from second to third and now reverse is out. Shifting solenoid?


Hello, I see you are having a transmission problem. I sorry to be the bearer of bad news.It seems as though you may have already known it but the problem that you have had with second gear, could have been a servo bad but with reverse going out it may be the servo an band in the trans. It will need to be overhauled, in my opinion, since the transmission must now come out. Please rate my answer, Thank you.
