My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello – with the vehicle safely supported to provide clearance underneath – in between the engine oil and transmission pan, there is a large, funnel-shaped aluminum casting (called the bellhousing), that physically mounts the engine to the transmission. At the forward vertical face of the bellhousing (immediately behind the engine oil pan), is an access plate – remove it. The engine flywheel/flex plate is now exposed. There will be 3-4 bolts, which go through the flex plate to the torque converter, which hold the torque converter to the engine flywheel/flex plate. Turn the crank from the front crankshaft pulley bolt (CLOCKWISE facing the nose of the engine) a bit, remove a bolt, turn the crank a bit further, remove the next bolt, etc. until all the torque converter bolts are removed. At this point, you should be able to slide the torque converter toward the rear of the vehicle 1/4-1/2" by hand. This will confirm that all bolts are out. You will also be able to rotate the torque converter by hand, without turning the engine. Remember this when re-assembling the engine/transmission, and it becomes to rotate the torque converter to line up the bolt holes in the flex plate. Proceed with the removal of the transmission.

No, it is not possible to remove a transmission without removing the torque converter. The torque converter is an integral part of the transmission system and is bolted to the flexplate or flywheel of the engine.
Loose torque converter bolts will accelerate the sound when the transmission gears are interconnected. The rattling sound can also result from a crack between the bolt holes. A loose bolt lowers the vehicle`s pressure output. For this reason, the gear shift tends to feel soft or delayed.
The impeller or centrifugal pump effectively flings the transmission fluid into the fins of the turbine that in turn spins or transmits the torque into the transmission.
It is possible to design automatic transmissions without torque converters but they require servo-controlled clutches for starting and stopping, and you must also add at least one additional fixed gear ratio to the transmission to make up for the loss of same by elimination of the torque converter.
The good news is, if it is just your torque converter that is having issues since it`s a self-contained unit, you may not need to replace or rebuild your whole transmission. Torque converters can be serviced or replaced as a single unit.
The housing of the torque converter is bolted to the flywheel of the engine, so it turns at whatever speed the engine is running at. The fins that make up the pump of the torque converter are attached to the housing, so they also turn at the same speed as the engine.
The casing of the torque converter is connected to the flywheel (which therefore spins at the same rate as the crankshaft) and within the housing is the turbine, the fluid centrifugal pump (or impeller) and a stator.
Clearance between the flexplate and the converter should be between 1/8″ and 3/16″, any more than this should be shimmed properly with an available shim kit. A good rule of thumb is to use an 1/8th” drill bit as a feeler gauge and make sure it slides in with little clearance.
If you keep driving your vehicle with a bad torque converter, the latter will cause considerable damage to the components within your transmission. You will spend a lot of money fixing those issues and still fix or replace the damaged or bad torque converter.
A torque wrench is a tightening tool.
It is a very sensitive and precise tightening tool, and should never been used to loosen bolts.
Rattling is one sound you want to be aware of. If you hear odd rattling sounds when you accelerate, this might be a symptom of a bad torque converter. The same can be true of whirring noises.
There are two types of fluid flow inside the torque converter. The first is the vortex flow, and the second being the rotary flow. In the below picture, the vortex flow is a spiraling flow which continues as long as there is a difference in speed between the impeller and the turbine.
It`s not that a performance converter makes more power, but what it does is allow your car to transfer power better. By raising the stall speed, or slippage, a performance converter raises engine rpm at launch, which increases power at launch.
The torque converter is what transmits that torque from the engine to a rotating driven load. In an automatic transmission car, the torque converter connects the power source to the load. Torque converters are comprised of five main components: the impeller, the turbine, the stator, a clutch, and the fluid.

Torque converters, as used in automatic transmissions for vehicles, frequently must be cleaned and, with present constructions thereof, it is not possible to disassemble the converter body to permit simple cleaning of the interior parts.
If you install the old converter on the fresh transmission and debris inside will contaminate the whole thing. Be sure you flush the trans cooler both ways as it stores a lot of junk when a trans fails.
The best way to remove a flywheel is to use a torque wrench set to 50 ft-lbs. Most flywheels will come off with less torque than this.

Place a pry bar, pipe, or some other piece of metal between the bolt head and the ground. Turn the flywheel in the direction of engine rotation until it makes contact with your prop, and torque away!

Flywheel to torque converter installation
ANSWER : Hello and thanks for contacting YourMechanic. The 2007 Dodge Durango could have had a different transmission. I suggest putting on the old flex plate that was on your old engine onto the newer engine. Then the bolts will align up with your transmission torque converter. Also, I highly recommend replacing the rear main seal on the newer engine that you are putting in since you will have access to it, to prevent any prematurely leaks. If you need further assistance with your vehicle, then I recommend getting in touch with a local expert to see if they can guide you through this.
installed tranny tightened it up, had to unbolt & realign torque converter & flywheel worked for 2weeks now have no gears
ANSWER : Hi there. It’s possible that the transmission, torque converter or other components is not properly aligned, or not the especially if you had to adjust the alignment initially. It can also be due to transmission fluid restrictions or pressure issues. Unfortunately, these are all issues that would be beyond our scope of services offered, so your best option is to consult with a transmission specialist to resolve these issues you are experiencing.
I need the torque specifications for the caliper bracket bolts, banjo bolt, and caliper slide bolts.
ANSWER : The caliper bracket bolts are 125 ft lbs. The banjo bolt for line connection is 35 ft lbs. The caliper slide bolts are 26 ft. lbs.
Ignition coil bolt can’t bolt down
ANSWER : The valve cover on that side of the engine has the broken bolt boss. The only way to secure the coil is to either replace the valve cover so you have the bolt boss to bolt down the coil, or to change the coil involved in the misfire.
Is it possible to remove Bracket bolts without removing caliper pins?
ANSWER : The complete bracket and caliper can be removed this way. I have seen this many times where the caliper retainer slide bolt seizes. The reason is no one lubed the slides and pins when they did the brakes in the past. This was avoidable if they lubed them on previous brake jobs. You can also purchase a new caliper with the bracket in most cases as an assembly. If you want to have a mechanic assist you with this, a certified technician from YourMechanic can come to your car’s location to inspect your suspension and help perform this task.
How much is a flywheel and torque converter? Are those parts worth replacing on my vehicle?
ANSWER : When the starter was diagnosed as bad the flywheel teeth the starter mate to when trying to turn over the engine may have broken or worn teeth and cannot engage each other anymore. Why the torque converter would need replaced I would need to know if the transmission has a shifting problem? I do not see why it would need to be replaced to get the vehicle to crank over. If you do not trust your mechanic word on the needed repairs then have a second opinion check from another mechanic like one from YourMechanic.
Need torque converter specs because I just replaced the transmission.
ANSWER : I’m not sure what you mean by torque converter specs. Torque converter end-play can be checked with a special tool and a dial indicator. This is done to determine the lateral movement of the turbine and stator. The repair information I have does not list this specification. If you have any doubts about the converter, I recommend replacing it. More often than not, the converter suffers contamination as a result of internal transmission failures and should be replaced anyhow.
