* TH350 (Turbo Hydra-Matic 350): This is a very common transmission. The drain plug is typically located on the bottom of the transmission pan. You'll need to get under the car to see it.
* TH400 (Turbo Hydra-Matic 400): Similar to the TH350, the drain plug is usually on the bottom of the transmission pan.
* SM465 (Manual): Manual transmissions have a drain plug, but it's typically on the side of the transmission case, rather than the bottom of a pan. Its exact location can vary slightly.
* Powerglide: This older automatic transmission also has a drain plug located on the bottom of the transmission pan.
To find it:
1. Identify your transmission: Check your vehicle's paperwork or the ID tag on the transmission itself.
2. Get under the car: Use jack stands for safety. Never work under a car supported only by a jack.
3. Locate the transmission: It's a large, usually cast-iron, case near the engine.
4. Look for a bolt: The drain plug is usually a standard bolt (possibly magnetic), though sometimes it might have a slightly different head. It's usually at the lowest point of the pan or transmission case.
Caution: Be prepared for hot transmission fluid if the transmission has been recently run. Use a drain pan to catch the fluid. Transmission fluid is hazardous and should be disposed of properly. If you're unsure about any part of this process, it's best to take your car to a qualified mechanic.
