If the transmission is healthy and any/all adjustments are done properly there should be no slippage.
There's no correlation. The AC won't cause the transmission to slip. If you're having transmission slippage, a bad torque converter is a common cause of it.
The fluid can foam and cause slippage and/or blow out seals.
Overfilling your transmission fluid can cause pressure which forces the parts in the transmission apart. This can cause gears, or bands to be pushed out of location, extra wear and damage. You can drain extra fluid off your transmission by using the plug on the bottom of the transmission. The fluid can be aerated from contact with the rotating parts. Aerated fluid in can cause slippage, lack of lubrication, and leaks. All of which can cause a major failure.
You should have no issues should you use a Sythetic transmission fluid such as Nulon Multi vehicle fluid do not use regular grade auto fluid this can cause power steering pump slippage and or failure
A 1994 Mazda Miata's automatic transmission may slip in 4th gear if the bands are heavily worn. When the bands become worn, they are unable to grip properly and cause slippage.
Faults are the boundaries between tectonic plates and are not the cause of earthquakes. The motion of one plate against another or the subduction of one plate by another can eventually cause a slippage, and it is this slippage that causes earthquakes.
This refers to an automatic transmission. My "96 has a transmission dipstick located to the rear of the engine, to the left (when facing the car from the front) of the brake fluid reservoir. To check it, park on level ground, start the engine and bring it to normal operating temp. Move the shift selector between all of the gears to be sure all are well lubricated. Check the fluid with the engine running. (being careful of any moving parts, of course) It should be within the indicated range. Too little will cause slippage or non-movement. Too much will cause foaming and loss of fluid. FriPilot
If the Yukon engine has high rpm while driving, check the transmission for slippage, that will cause the engine to over rev. The overheating could be caused by the high rpms.
It's possible but VERY unlikely. If the differential losses all it's fluid, it is possible for it jam up, but there are other points of failure along the way besides the transmission. even if the transmission is suddenly stopped, it should not cause any permanent damage unless there is a LOT of torque involved.
A transmission that is over full (automatic particularly) will fail very soonA tiny bit over will not cause trouble...BUTAny more will cause oil foaming, clutch slippage, oil pump failure, spraying oil out of vents and possible vehicle fire.Manual trans will do the same thing but are more tolerant to minor over fills.
Clutch slippage can cause an engine to overheat by running the engine at higher rpm's than what it is recommended for the motor. Excessive heat in the engine can cause the head gaskets to leak building up heat in the motor. There are inexpensive kits to test whether your headgasket is leaking or not.
