If the liquid in an automatic transmission has a burnt smell or is polluted by parts of a material of plugs or from a friction, probably, transmission major repairs is required.

Low level of a liquid can be at the bottom of many malfunctions as air gets to a liquid, and the suspension of a liquid with air becomes compressed that leads to chaotic change of pressure and infringement of work of couplings and tape brakes.

Also the raised level of a liquid leads to that rotating gear wheels of a transmission shake up foam which leads to the same results, as air which has got in трансмиссионную a liquid.

In any case air vials lead to an overheat and oxidation трансмиссионной to a liquid which, getting to the valve, breaks work of coupling and brakes. Foaming can lead вытеканию to a liquid which can be accepted for liquid leak.

Reliably insert щуп for level measurement.
