Yes Dear
Bruce, in previous oil discussions, it was decided there are several new and improved oils available at custom shops. I changed my trans oil after the cars 18 year soak in I'm sure was the same old who knows what put in by who knows who how long ago.
Ran the El Cheapo stuff in the VWs and the Falcon 3 speed with never any problem except for the fact the Falcon non synchro 1st could not stand up to MRS anyway as she had to crunch it in every non Cali stop she did, me I rolled em in 2nd like any self respecting native.
Back to oils the cheap stuff was put in as no other was available at the time. I was so darned anxious to drive it "insert pic of Gene Wilder as Dr. Frakenstein its alive." I have changed out the rack fluid as that was kind easy in Tiger fixes, but haven't gotten around to the trans.
This year I found a El Cheapo GL4 oil that had the Olefin Sulfate added just like the GL5 oils, so wanting to point out to the group simply finding a GL4 did not mean the stinky sulfur additive was not added, we have to read the label these days.
Doing more reading it seems that the chemist types put in another additive to counter act the nasty brass vs additive problem.
Just a point of discussion, fellas its an old trans that needs a refresh hopefully sooner than later the trans brass are available unlike the rack brass parts ''add pic of the You want it When laughing cartoon guy," from you old favorite shop, them be unobtanium.
The key will sit on bench partially submerged till it boils over or foams at the mouth or gets spilled.
