What causes a bad torque converter on a Jeep Wrangler?
Your Jeep Wrangler’s torque converter is responsible for converting the energy generated by the engine at the flywheel and transferring it to the transmission, creating a bridge between the engine and the transmission. In the Jeep Wrangler, a bad torque converter is often caused by bad transmission fluid, worn clutches, bad seals, or loose bolts.
When did my Jeep Wrangler start having transmission issues?
Transmission only started being an issue about 1 1/2 years ago and has been getting worse in the last 6 months. Contacted a place in Michigan that specializes in Jeeps to see what he has new or gently used. Thank you for your help, I’ll update when I know what I am doing.
Why do you need a locking torque converter?
Nearly all modern automatic transmissions have a locking torque converter. A locking converter has clutches in it that lets the transmission make a physical connection with the engine. This eliminates operating inefficiency when it is at high speed (usually after about 45 miles an hour).
What causes the stall speed of a torque converter to change?
The torque converter “stall speed” is the speed that the engine needs to be turning before the torque converter will begin engaging the transmission. When a torque converter is malfunctioning it can cause this stall speed to change and feel like the transmission is slipping.

If there are black flecks present in the fluid, then you should replace that also. Doing so might just end up saving you a lot of money.
How do you remove bolts from torque converter?
The engine must be turned to rotate the torque converter to access all the bolts one at a time. Establish whether there is a cover on the bellhousing for use in accessing the torque converter. Disconnect the negative terminal on the battery, using a wrench, if there is no cover. Raise and support the vehicle on jack stands.
How do you remove a transmission from a jeep?
Remove the bolts holding the transmission to the transmission crossmember. Remove the bolts on each end of the transmission crossmember to drop the transmission. TIP- Be careful as the transmission will lean way back because it is only supported now by the engine mounts!
How much does it cost to replace a torque converter?
He is certain the torque converter is bad and the fluid I had changed 4 months ago is already brown in color, which is likely the material from the converter. They gave me a quote of $1200 to replace converter or 4k for transmission, also gave me the option of buying my own refurbed tranny and they would install for $750.

What happens when a torque converter is damaged?
If the torque converter seal is damaged, it could cause the transmission fluid within the bell housing to leak. When that happens, the torque converter will be unable to provide a smooth transfer of power from the engine to the transmission. As a consequence, there could be overheating, slippage, higher stall speeds, among other problems. 2.
Can a slipping torque converter wear out the transmission?
A slipping torque converter will wear out the transmission very quickly. In some cases, you may have temperature sensors that cause the transmission control unit light on your dashboard to flash, which indicates that your torque converter is slipping and overheating the transmission.
How to test a torque converter without uninstalling it?
Remember to not release the brake pedal. With one foot on the brake pedal, press the accelerator all the way for 2-3 seconds with the other foot. Be careful not the exceed 5 seconds or the transmission could blow out.The stall speed is the RPM the engine maxes out at.

What’s the difference between a torque converter and a transmission?
Whereas, a manual transmission clutch provides a direct physical connection between the engine and the transmission. That’s why at a stop the clutch must be disengaged from the flywheel. The torque converter bolts to the input shaft of the transmission and uses the same hydraulic transmission fluid that the transmission uses.
Why does my torque converter run at high stall speed?
High Stall Speed – A torque converter’s stall speed is the engine rpm needed for it to engage the engine. This is often one of the symptoms of low transmission fluid. A bad torque converter will often run at a higher stall speed.
What are the signs of a torque converter problem?
Another sign of a problem in the torque converter is if your car’s temperature gauge indicates that there is overheating by flashing a transmission control unit light on your dashboard. This sign may be triggered by a decline in the fluid pressure or a malfunctioning solenoid. Slipping while you’re driving can also lead to overheating.
What makes a torque converter shudder at low speed?
Torque Converter Shudder Problems. A torque converter is the fluid coupling between an engine and transmission that allows the engine to idle at low speed without engaging the transmission. A torque converter uses an engine-driven turbine (fan) to push fluid through a matching turbine attached to the transmission.
Which is the best brand of torque converter?
All auto-parts retailers sell some sort of transmission additive designed to thicken the fluid. Lucas brand is the most popular and is recommended by specialists like Mr. Transmission, but is usually the most expensive.
When does a torque converter need to be replaced?
Unless there is physical damage to the converter or transmission, shudder is a fairly easy problem to solve. Once the transmission fluid has been overheated enough times, it becomes permanently de-polymerized and need to be replaced.
