When it gets to that sort of situation even a repair that doesn't 100% fix the problem, but vastly improves the situation can count as a win. Great detective work.
Would the thickness of the paper gasket cause a enough of a rise in chamber volume to affect pressure and prevent it not been a 100% fix?

The shift is a little more stiff because it's pushed the lever against the pan a bit. Overall though now if I lift off, it changes. Mostly. Phil |

Somebody has suggested International Harvester Hy-Tran oil. It's SAE 10W-30 compared to this Valvoline which is 5W-15 or thereabouts.
Hy-Tran is expensive. I may try using 30W engine oil first because it's cheaper as an experiment. If it doesn't work out I can at least drain it and use that in the lawnmowers...

I would have said I love your determination on getting it right, but I think you're a bit like me and its not just determination that drives you but more something compelling you...You just can't accept, like me, that something won't work as it should. But maybe I'm wrong here, in that case: I love your determination! ;-)

ia that trick shift stuff too expensive phil ? Yes. This Dexron wasn't cheap either, at $34 for 3.7 liters (given it takes 4 bottles of the stuff). I'm trying to avoid too much unnecessary expense at this point. I'll let y'all know how I get on with heavy machinery oil. |

I know it has the capacity to work better- it must have new because people wouldn't have accepted it doing what mine does. It'll work right. Eventually. It's frustrating though, because I cannot get inside it more than reading main line pressure. That has always been in spec. Being limited to simply changing things inside, and then trying the result is tiresome and can lead to annoyance. Simple bullishness is keeping me going to resolve what is wrong or what I have done wrong. Phil |

Oil change.  1500 miles and it's particularly dirty. |

Welp. Wish I hadn't taken the heater fan apart now.  It is quite comprehensively broken. One of the brushes shattered and then it all overheated. Ordered a replacement, should be here Tuesday. Might look to see if anywhere local has brushes tomorrow. |

Just how little time it lasted however was disappointing. Still, I'm going to try and revive it as a backup and put the new one in when it gets here. By which time the cold weather's going to have gone. |

I bought some brushes and modified them to fit.  Seems to have worked.  That won't last, but it'll run long enough that the new motor should get here. |

The commutator is very far off round, one pad is badly burned. It won't last. |

As said with an off round and burnt comm it wont last long , the brushes will bounce and arch out , if it wasnt burnt its easy to true the comm on a lathe , we do this daily at work , re cut the mica between the segments and its usually good to go , do a lot of 10 and 12 seg ones for wipers and fans This is a go faster one i did for my wipers , wound as 10V not 12V , Runs a fair bit faster but still cold - after all the armature has no clue what volts it is , it just reacts to what its being fed  |

This one ran hot enough to melt the solder making contact between the armature winding and commutator pads.
I don't have a lathe; I don't think turning it in my drill will yield adequate results so I just bought another, wound for 12V instead

Filled up with 20W hydraulic transmission oil. Hot shifting seems to be better,need to get some miles on it before I pass final judgement.
2-3 shift is definitely smoother, which is welcomed at any time.

A few observations, having gotten the gearbox nice and hot today.
It'll change better once it's changed gears a few times.
Cold it's great.
So, I think I'm gonna bump up the oil weight and hopefully that'll fix it.
Phil
