    manual transmission additive

    Just checking to see if any one has had experience with Moly Slip manual transmission additive. Better shifting? O/D compatible? Cooler running? Less wear?

    It's time this spring to change my fluid and just wanting to know if it's good stuff.

    Thanks

    My opinion: It is highly unlikely that this "snake oil" would do anything good in an Overdrive, you do not want that much "slippage" in the O.D. or the synchromesh unit in the gearbox. Others may vary!

    Try to find GL1 80W-90 Gear Oil at your NAPA Auto Parts Store.

    Do not use a GL5 or a GL5 that replaces (or includes) GL1, GL4.

    A GL4 ONLY rated oil, will work in a pinch, also 40 Wt [u]Non-Detergent</u> Motor Oil is recommended in the Manual.

      What Rich says. Also, 80 [u]mineral</u> oil is recommended and either 40 wt non-detergent or mineral oil are available at our local far, stores.

        Also at FBO's (airports) straight 40 and 50 weight mineral oil is generally used to break in newly rebuilt piston engine aircraft engines.

          Right-O, Rich. The NAPA Part Number for a one-gallon jug is #65-201. (Ironically, this is the lead-off item in the March 2009 Co-Operator, sent to Ann for composition in early January!) BP

            MolySlip products use molybdenum disulfide to reduce friction, of course reducing heat and wear. Been around for close to 50 years.

            Went to there website www.molyslip.com and learned to my surprise that although it was developed by the Germans during the war, most of its North American distribution seems to be in Canada! The U.S. MUST have something similar.

            Whoever created the website did a crappy job, and I think you need Adobe Acrobat to see it all, but, some testimonials are available without it. Especially read the one from FinishLine Racing School in Daytona, Florida. No tranny or engine failures in 7 years!

            The stuff is no snake oil and they do make a manual transmission supplement (note that it is a supplement, an additive).The instructions point out that it is not for use in any place that depends on friction to produce motion (like limited slip diffs, automatics, wet clutches).

            I'm tempted. The engine oil supplement works and produces about 3% more horsepower and increases gas mileage. See City of Brampton testimonial.

                I use MTL-90 in the car below and you can shift it with 2 fingers, hot or cold.

                    Dan, Tom, and Mike: Agreed on the "goodness" of Redline MT-90; its a good product.

                    However, I spent some time on the Redline website and cannot determine if that product is OK for the overdrive portion of our transmissions. Have any of you guys used it for a complete fill of an overdrive transmission? Results?

                    Thanks. BP

                      STEWDI, the overdrive transmission does rely on friction to work. The over-running clutch within the overdrive has a number of steel rollers on tapered ramps within a drum. It relies upon slght drag between the rollers and drum to force the rollers to climb the ramps and wedge tightly between the ramps and drum to transmit full torque.

                      I don't know if moly additive would stop it from working, but it might possibly cause delayed or harsh engagement.

                      And getting it OUT of there, if it proved to be inappropriate, would be tough.

                        Thanks, guys.

                        I guess the right course of action is to not add anything until we find out of if a moly additve or Redline would be detrimental to overdrive operation.

                        This forum is awsome.
