I remember Marvin the mad(727) scientist from Chrysler Power years ago advocated adding motor oil to the trans for it's improved lubrication qualities even going as far as using all motor oil I have added a qt here & there & no problems mainly because I was out of trans fluid & going by him way back saying that it was Ok.

It does sound totally ludicrous which is why I had to try it 30 wt would for sure be higher viscosity than atf & if it'd be better(for lube & function) I'd also think Ma would have tried it & used it if it worked better so I dont know...

Would you put transmission fluid in a motor?
Yes I will and have, cleans out a nasty set of lifters in a jiffy. Heard of the motor oil in a trans but never tried it. Are you sure thats what it is or just some burnt black tranny fluid?
Might clean out your lifters but I bet it will play h#ll on your bearings.

When the 727 was new and transmission fluid wasn't as sophisticated as it is now many racers ran straight motor oil in the 727, either 10-30 or straight 30 weight.

Was in the Air Force for 20 years, as a Vehicle Mechanic. Most of the larger trucks that had Allison transmissions in them, used 10 Wt (Hydraulic oil). Never had any major failure that I can remember because of the fluid. I know it's not engine oil, but it's along the same lines with different characteristics.

Tranny fluid is a poor lubricant
I would think that too. But why would the factory switch from 90 weight to atf in the manaual trans.
