Tom,
I switched to Redline MTL in both my transaxle and front differential
and really like its performance, esp cold weather.  Its been in the
boxes for about 10,000 mi now which isn't much of a testimony, but
others on the list have been using the same oil much longer on old
gearboxes with no problems.....

I was experiencing a noisy trans and tried the Redline oil as a

***Maybe the problem wasn't 'fixable' with oil--sounds more like it was
related to a developing gear problem you stated below.

***There is about 1.5 qt of the ~3.2 qt capacity of the trans that is
trapped, so only getting out 1.5 to 2 qts sounds correct.

***before i switched to Redline, i had similar questions and asked their
tech rep as well as other van list members who use redline.  My
conclusion was that early synth oils may have had this problem, but
modern synthetics do not.  Again, your 'oil loss' is probably acounted
for by the trapped oil.

***...doubt it.
