which hydraulic fluid

[dazedandconfused]

It depends on the convertor builder and how its setup. On guessing tollerences are so close with the triple disc it burns the clutches up.

I can see that,but you also have to ramp up lockup pressures to even utilize a multi disc converter with regular fluid. I can see where it could get hairy with the thick hydro fluid.

I'd doubt any harm would come from running it in a plain jain converter tho,LC or not.

That's what I was thinking Ellis. I'm trying to gather more info but all I keep getting is don't use it.

I could see it being an issue with not releasing fast enough. I'm wondering with the thicker fluid and higher pressure it can't release fast enough to keep them from slipping since they lock\unlock so often. I also wonder if the people burning trans\converters up if they are running straight hyd fluid or with lube guard also. If you run lube guard it might not be a problem with lock up converters.

[dazedandconfused]

Most people I've chated with said they run 50/50.

50/50 atf4 and hyd fluid? With nothing else?

[dazedandconfused]

Yes

Hydraulic fluid has some kind of additive package in it......think of the hydraulic pto's tractors have. The few I've seen have been nothing more but clutch packs and planetary,same as an automatic trans.

The lube guard or Lucas wont hurt anyway but with so many running it with out I'd say it would be necessary.....just a better idea or CYA material

Going a little off topic here but since someone mentioned the clutches in a lockup convertor, would anything burn up if you never used the lockup (when using a 47rh, 47re, etc trans)?

I don't know about dodge but.....GM tranies don't like it,with them you don't get full cooler flow till it's locked in.
