46 How to Repair a Cast Aluminum Transmission Case
Note: Due to the thickness of the aluminum, we recommend using oxyacetylene torch and a size 3 or 4 tip. Propane or MAPP gas will not heat the large mass of aluminum sufficiently to flow the rod. Super Alloy 1 will not bond to cast aluminum, Super Alloy 5 is required for this application.
Prepare the cast aluminum transmission case by beveling the crack with a grinder. Beveling is necessary to achieve full penetration of the aluminum filler rod, which replaces the removed material and bridges the gap.
Broadly preheat the cast aluminum with the torch, front and back, continually moving the heat. The base metal will look soft and begin to dimple as it reaches the working temperature. Apply the flux with the end of the rod and watch the transformation from powder to liquid, indicating the cast aluminum has reached the 600°F working temperature. Add more rod and flux, flowing the deposit before applying to the next section. Work your way down the part, filling the gaps in the cast aluminum incrementally until the entire crack has been filled.
This cast aluminum transmission case was repaired in less than 2 minutes with roughly $1 of Super Alloy 5. The resulting bond is strong–30,000 PSI–and Super Alloy 5 can be drilled, machined, tapped, threaded, bent, anodized, or plated and is a perfect color match to the aluminum.
TIPS:
- Always keep flux bottle close to the repair area, because every time you move your torch away the aluminum drops approximately 100 degrees per second
- Always angle torch in the direction of the crack
- Thick aluminum requires oxyacetylene, oxypropane, oxynatural gas, or oxyMapp gas to heat the base metal to the required 600°F. If the flux is not liquefying, it is because the base metal is not hot enough

In vehicles with automatic transmissions, a metal disc called a flexplate, connects the crankshaft to the torque converter.
So, a flexplate, as the name implies, serves as a flex-shock device; between the torque converter and the engine crankshaft.
Broken Transmission Bands
A flexplate consists of a steel circular disk with perforated holes. And, is also balanced to improve, smooth running. Consequently, flexing allows it to respond to small differences of alignment, between the engine and the transmission.
Cheap Transmission Rebuild
Flexplates actually consist of two parts. The flexplate and the ring gear, fitted to the outside of it.
Broken Transmission Shift Cable
The starter motor, engages this ring gear to start the engine. There may be times that you have to remove it. But, if you have to remove the flexplate, it must go back on the same way. Because, balancing is very important.
What Happens When It Fails
The bolts are torqued in a crisscross pattern, according to the manufacturer's specifications. The torque converter used with an automatic transmission, acts like a flywheel, smoothing out engine pulses.
Flexplate Cracking On Various Engine Applications Is Common
The cracking on these flexplates can be seen, either around the crankshaft or torque converter bolt hole patterns.
What Can Cause, A Cracked Flexplate:
- Out of balance engine or torque converter.
- Bad starter drive, can cause teeth or ring gear to wear rapidly or break off.
- Teeth can also break, when engine is running and starter is engaged.
- Failure to torque the bolts, to proper specifications and in proper sequence.
- Failure to use starter shims, where required.
- Poor quality parts.
- Missing Dowel pins.
A loose bolt on a flexplate or a crack between it's bolt holes can result in a; knocking or rattling sound. The sound is very similar to a bad connecting rod and is often, misdiagnosed.
The flexplate can become cracked over time. As a result, this can cause the it, to wobble. So, you might notice rhythmic clunking or grinding noises, while the engine is running.
A misaligned flex plate, can also keep the engine from running smoothly. So, if you suspect you have a flexplate problem, there are a couple ways to investigate further.
Broken Transmission Music
So, if you listen to the transmission bell housing with a stethoscope, while the engine is idling; any sounds coming from inside the bellhousing indicate, flexplate problems. Some bell housings have an, inspection port. If so, remove the inspection port and shine a shop light on the flexplate for a, visual inspection.

Some bell housings have an, inspection port. If so, remove the inspection port and shine a shop light on the flexplate for a, visual inspection.
Starting Problems
A warped flexplate won't engage properly with the starter motor. So, when you are starting your engine listen for, rhythmic bogging down of the engine, during starting. Consequently, the teeth of the ring gear, can become damaged over time, causing a grinding sound.
Ring gear problems can damage the starter motor as well. So, if you find you have to replace your flex plate, you might want to check your starter as well.
A cracked flex plate is almost always, a sign of other problems. So, if not properly diagnosed, it will occur again and often damage to the transmission may follow. The same things that caused the flexplate to crack, can also cause transmission problems. In addition, damaged and leaking front seals; and front transmission pumps are common symptoms.
Conclusion
So, a engine making noise when starting, often indicates either a; starter failure or broken teeth on your transmission flex plate. Also, some cars require several hours to replace the starter and hundreds of dollars, for a replacement part.
However, if your car needs a new flex plate, it's a much bigger issue. Because, the transmission must come out, to replace the flex plate. For instance, it's $1,500 and up, to replace a flex plate, in most vehicles.
