Hi Roy, now you have me concerned, I also have been running aeroshell 41 5606 for the 12 months Ive had my convert for but have not yet sampled the tank, will take a sample tomorrow. My convert gets used weekly and so far only travelled 12000 kilometres with it and would like to think the fluid gets enough heat to dissipate any condensation . I live in a warm dry climate in south Australia and condensation is not really an issue. Perhaps your in a colder damp climate that may be causing you issues but will check it out tomorrow .Bill
I've always just used the closest equivalent to the factory specified Dexron II. Right now, that seems to be Dexron III/Mercon. I'll be changing all of the fluids soon and plan to use Redline D4 ATF this time. https://www.redlineoil.com/d4-atf
engine number 471 .it has the early long wheel base, 8 inch headlamp get monitor size
Thanks Charlie. Do Guzzi specify Dexron II for the Cali II Converts? They specified Dexron for the Round Barrel models. (That is first generation Dexron with whale oil, no subsequent upgrade numbers)keyboard symbols copy pasteIIRC previous discussions centered around folklore that said Dexron II & III with "friction modifiers" are too slippery for our old torque converters, hence the use of Mil 5606 which is a simple mineral oil used in hydraulics. My understanding is that the slippery friction modifiers are to enable smooth shifting of sophisticated self changing gearboxes which are full of clever valving and small oil passages. The matching TC's must be built to closer tolerances, and maybe different shaped vanes, to work with this slippery stuff??
Hi Roy, dipped my tank this morning after 12000km and am happy with what my aero shell 41 looks like. Maybe you have internal hose problems. Apart from the atf pump seal allowing engine oil in from the timing cover I cant think of any other way contaminant can ingress the system. If there was a fault at the convertor you would think there would be fluid residue around the bell housing
Glad you got it sorted. I have a 76 convert that I'll be putting back on the road after 10 years. I'll try your method above. I also thought of trying regular power steering fluid. Years ago they recommended atf dexron or dexron II in power steering units. I can't seem to find the specs on ps fluid but I thought of trying it just to see how it would work.
Very nice! Here's my B,1398 and the die cast C,10545 which I enjoy riding. It has just turned over 10,000 miles and is having a service. You may notice that they are both twin cylinder Comets with separate gearboxes.
Is that a Seeley frame there Roy?
No Muzz, it a replica Egli that I built. One day, when you least expect it, I'll bring it to a Guzzi Rally and show you. I think it's eligible, it has all sorts of Guzzi bits, Sport/Eldo front brake lever, V50 Carbs, tank rubbers, fork stem bits etc.
