I have gotten the vehicle up to temperature and went and checked the level on the dipstick, which seems to be fine and fluid seems to be new


if you can chime in and let me know what diagnostic protocols you would take I would greatly appreciate it. I’m way in the middle of nowhere in Texas so taking it to a shop that would have the right knowledge is going to be a bit difficult so I’m going to see what we can do while out here or having a general mechanic help out


it’s a 1994. now we will go into one two and three gear and I can drive the third gear up to about 60 miles an hour. I’m wondering if it’s not like a solenoid or something simple how far would I be able to limp the coach let’s see if I needed to get to a mechanic shop that specializes in the Allison  is it advisable to drive in lower gears for a longer time will it hurt the trans? thank you guys in advance

In the meantime I saw that a United 767 hit a bread truck and light pole in New Jersey.  Yikes!  I had a much better day than those guys! Big Grin

Replaced nut and double nutted jammed nuts together so hopefully will not happen again
Motor does not make boost in neutral, had to brake torque it in gear to check for boost
Drove back to Tampa after the 500 and every thing was back to normal]]>

Went to crank it up today.  Turn the key and…. Nothing.  No crank. Isolated each the chassis batteries and checked voltage and they were about 13.6  House was 13.6.  Batteries were merged

Checked voltage at the starter and it was 13.6 positive and ground with the meter ruling out bad battery cables

Checked the starter relay where the rear start switch is, red on the small wire of the relay, and black to ground on the battery and turned the rear start switch.  It went from 2.7mv (switch off) to 6.0mv (switch on) and 22mv (switch in crank position).  I would’ve thought this would have had volts not milli volts going thru it.   

I’m thinking the relay is bad??  I’m going to jump the relay next time I’m out where I store it.  But does anyone have the part number for this??  So I can have a spare??  Or confirm that it’s bad?  Or can anyone shed any other light on the subject??

Thanks

I'm about to put the whole thing back together with the old seal cleaned up and oiled, reassemble everything and limp to Vegas, because we are 80 miles south of Elko, NV and I can't get any help here. We are going to pull over at every rest area and check fluid levels and top off accordingly. 

Oh, if anyone needs it, the retaining nut on the yoke is 2-3/4 and it took my 1" pnuematic to Crack the torque. 

Thanks!

I am replacing my cap, because its broken. At the same time I'm doing the crankcase breather filter. You can't take it out the top of the filter housing because it is just under the bathroom floor. You have to take the entire housing off to get the filter out. 

A CAT technician, when asked about this filter, said that the filter us a service item that gets changed with every oil service. Mine looks to have never been changed. We'll see when I get it off.]]>
