Please help anyone. Bought a 1996 Cobra last year and finally got around to changing the differential fluid. It has a T/A girdle with a fill and drain plug.

No problem draining. But I'm trying to fill it and it appears to be eating the fluid. I've put in 6 quarts so far, and I'm just starting to top off. The Chilton's and a number of websites list capacity at 6.6 pints, I'm double that already with no end in sight.

Please help, she needs to get back on the road.

Thanks.

Are you checking it by the hole in the cover or the plug in the front of the rearend ? Just changed to a after market cover and mine took 2 quarts.

Just did a gear swap recently (4.10s ROCK!). I don't know about the 96 Cobra, but my 02 GT takes 4.25 pints. That came to 2 quarts (of RP 85w140 synthetic) plus the friction modifier.

If your Cobra is supposed to take 6.6 pints, then only put in 6.6 pints. It sounds like you have overfilled it. Good luck.

wth a girdle it will hold more fluid but not that much more, you need to check the oil level at the fill plug on the left side of the housing, not on the girdle
