Automatic transmissions have something called a torque converter - it's a donut-shaped device between the engine and transmission, that allows the engine to rotate at a slightly different speed than the transmission, in order to build momentum, add power, etc.
Modern torque converters are designed to lock-up under certain conditions, meaning the engine and transmission become coupled, like they would be on a manual transmission. This reduces wear and is better for fuel economy, when acceleration is not needed (ie. on the highway). If the converter is "lockup hunting", that means the transmission can't decide whether it should be locked up or not, so it's going back and forth. Probably time for a Transmission Fluid change. Be sure to have them drain and replace the fluid in the torque converter as well. Or the transmission may be worn out. Another way to tell is to pull the transmission dipstick and smell the fluid. If it smells burnt, it needs immediate attention. Pulling trailers or plowing snow often will do this.

Where is the plug for the lockup converter on 2000 dodge neon?
There isn't a drain plug on the converter.
Does 1999 dodge 5.2 have a lockup converter?
YesYes
Will a 1992 dodge Dakota transmission interchange with a 1993?
Yes but, the 92 is non lockup and the 93 is a lockup torque converter.
What is lockup solenoid?
Lockup Solenoids refer to electronic gadgets in automatic transmissions that lock the torque converter in certain circumstances, such as at highway speeds.
Location of torque converter lockup plug?
on a 200r4 or 700r4 its on the side of the transmission.
What are the advantages to a lockup torque converter?
Lower trans temps and improved fuel economy.
On a 93 Oldsmobile Cutless Cierra the lockup torque converter doesn't work Why?
low fluid level
What is 1997 fault code p 1742 description?
it is a failure of the solenoid for the torque converter lockup in the transmisson.
Will low transmission fluid level cause your transmission to jerk?
yes it will especially when the torque converter is going into lockup
Why does your 81 Chevy 4x4 350 auto trans make a lurch and knock when it comes to a stop?
Possibly the lock-up torque converter solenoid is sticking. Disconnect the wire to the lockup converter.
Can the torque converter be emptied or does it have to be rebuilt for your 350?
You can empty it out and change the fluid if there is nothing wrong with it and the stock stall speed will still work with the engine you will be putting in front of it. It's basically a fluid coupling. Since it's full of fluid and the fluid does most of the work, there is very, VERY little wear inside a converter. The only exception is if you have a lockup torque converter. The clutches inside lockup converters DO wear out and ultimately fail.
Where is the lock up solenoid on a axn4 transmission it is not getting a signal and it will not shift in to over drive?
The lockup solenoid does not control OD shift. The lockup solenoid controls torque convertor lockup. Torque converter lockup isn't a gear at all, but a fuel saving function that kicks in when you are cruising, which is a clutch in the torque converter that locks down and overrides the fluid coupling so you dont loose engine engine torque due to the normal fluid coupling of the torque converter. In effect, it overrides the torque converter completely, and provides a direct drive from the engine to the input shaft of the transmission. TC lockup does occur in OD, but it is a separate function. OD is achieved in the AX4N when the OD band holds the front planetary sun gear stationary. This is done by the OD servo and piston assembly, when fluid is directed there through a valve in the valve body. You could have a problem in any of those areas causing you not to have OD.
