Scubaman,
I was researching the Baker Tech Info for some of their clutches (it appears that our stock are very close if not a Baker Street Perfomance type). In the reading of their install I noted that it said fill with primary fluid, however they (Baker) indicated that ATF (Dextron/Mercon) will provide better results.
So I figure what the hell, give it a try-so I did and I must say it did seem to be more alive on the clutch. May be due to have pulled it all part and cleaned out everything and then install fresh, not sure. I will say it makes sense though since the Basic of a AT is very similar with wet clutch and gear and some cases chains.
As far as the adjustment. I was speaking of how much to compress ther diaphrame spring too insure the proper pressure. After re-reading the SM, I found that it said that the diaphrame should be .020-.040" from flat when new and that if it exceeds .068" when properly tighten, the clutch may need to have plates and/or pressure plate replaced. My problem is that I could not find what the proper torque was when the 4 bolts of that hold the pivot plate to diaphragme spring (which in turn compress the pressure plate) was. After researching, I found that the Baker for the Street Perfomance was indicated at 200 inch pounds.
So I torque the four 5/16 X 18 X 2" bolts (after putting some Red Loctite on them) in a cross pattern slowly to 200" pounds of torque. After I was done, check the spring heigth with a depth micrometer and found it to be at .032" +/- .002 all the way around.
After getting it all back together, new clutch cable adjusted, etc, went for a nice little ride and was very pleased.
Not sure on the ATF but it indicated Dextron-Mercon. Would love to hear from Puppy Farm any input on thoughts on the ATF. Will say pleasantly surprised and makes sense.
Here is the Install for the Baker Street Performance Clutch which appears to be very similar to ours, they show it has 9 Plate but mine is 12, I know the newer ones are 9 Plate though on the BD.

Hope this helps.
