Thread: disappearing tranny fluid

Tweet

I've got a problem with my tranny, for some reason no matter how much fluid i put in it, its all gone within a couple days. At first i thought it was leaking, but there is no puddles, can anybody help me out?

First I would check your trannys vacume modulator, if it has a hole in the diaphagm, the engines vacume will suck the fluid up the line and into the intake manifold. Sure fire way to check this is to pull the vacume line at the modulator end and if you see any fluid come out thats your problem, to fix just replace the modulator canister. S

Is there any white smoke coming out your exhast ?If your burning transmision fluid it should smoke. Also check your antifreeze I have seen the trans cooler in the radiator fail and push transmision fluid into the coolant. carlg

The new cars with cats cut down the smoke out the pipe big time,when theres a problem.
