I you need to find the thread size for the machine thread end of grease gun flex hose and forgot like I did, it is .437” x 28 tpi, not a common hardware size unless you are lucky. Might have to be ordered.

7/16=.4375, just out of curiosity, what are doing to your 47rh? I am using the same trans in my build...

 

[Blackduck596]

Odd size, a UNEF thread. Usually just use in 1/8 NPT on gun hoses.

Grease gun hoses use .125” pipe on on end ant this on the body end, who knows why, perhaps the high pressure?

Boomers,
Using pressure to engage OD above 45 mph(pressure) or so, and off below, manual switch also; turn off LU at say 10 mph(pressure) so don’t stall engine if forget to turn off manually, manual switch also.

That's interesting... manual switching... I was considering just using toggles and wiring a LU kill thru the brake pedal... or are you saying your just using the gauges to monitor pressure and still using toggles...

Right, around town, no need for OD, no need for LU, so leave switches off. Once up to 40 or do, enable OD by switch buy let preset pressure switch do final enable, upon slowing, same pressure switch turn OD off or by manual switch. Same idea with LU, manual switch turn on, pressure switch turn off at 10 mph or so, so as to not stall engine. Use adjustable pressure switches with gauges in cab(thus the grease gun hose) to determine and adjust pressure gauges.

Got it...!!! sounds like a great idea...

 

[boomersrule55]

Where do you tap in on the trans to get the pressure readings?

 

[edpruss]

Right side, .125” pipe plug about half way up.

ty Ed, I will check that out...

I would say you forgot to put a shut off valve between the 100psi gauge and test hose. Why needed....??? if you try and test a preasure over 100psi range that gauge will go west real quick.......Why need 2 gauges....???

Two pressure switches are needed, one to enable OD at 45 or so, the other to shut off LU at 10 or so to not stall engine. Both these MPH settings will probably be adjusted upon use. Both these pressure switches are after the manual switches, no manual on, no OD, no LU.

Hello Ed, I read that it is not good for the trans to be in lock-up when up or down shifting, so will your set-up still be in LU when dropping out of OD into 3rd, 2nd?

 

[edpruss]

Have to figure that out, figure out how factory does that.

You might try the transgo tech line... I have a 47rh behind my 95 12v dodge 4x4, I thought it only locks up in OD, transgo has a kit for the 47rh and re, that claims you can lock up in any gear, not sure if this will work for what your trying to do...
