The Great Tranny Killer Returns

SVX-FF · #1 02-04-2008, 05:28 PM

Well after only 6 months I have managed to start kill tranny #5. the tranny has started to flare 2nd to 3rd and 3rd to 4th. Lock up works. When the flares started the tranny started smoking a lot. I have narrowed it down to the right vent tube. WHY?

Any takers.

One more and you'll be tied with me

Fluid pushing out of the vent tube??? Overfilled or getting real hot???

I gather that after five rebuilt/repaired/stuffed about with transmissions, you are asking what is the problem.

Why would it be just the one vent tube?

I am also starting a collection for a mt conversion.
or a new car.

Sounds to me like something external to the tranny is causing them to go out. Either you have a restricted cooler, restricted cooler line, or you have some sort of electrical problem such as the dropping resistor or it's wiring.

One vent is for the diff, one is for the trans

well if I drive like a grandma, letting Yugo's oout accelerate me, then there is no smoke and shifts ok. There is still a little smell and flare under normal driveing.

Steve, I don't think I have any magic answers for you, but I have some ideas.

If the oil is escaping or being driven from the trans, then it would easily make its way to the cats and create smoke.

The only place I'm confused is you say the right vent? I would expect transmission oil to be getting out the left side where the filler is at.

On the right side is the differential and they have separate reservoirs, no connection [by fluid] to your trans.

With your flaring going on there must be wear on the clutches or the brake band is slipping. Or both.

As Hondasucks mentioned, the problem could be external. If an oil cooler line or oil cooler is blocked or partially blocked it will create internal pressure that would force oil up the filler pipe. You need to check into this.

Also you are running 4.44 transmission. I'm not convinced a 4.44 trans from a Legacy is built "tough" enough for the torque the SVX can dish out. What I'm really saying is if your tranny guys are replacing the clutches with standard Legacy clutches, this could be part of your problem.
