Old buses are like wife's when you get one you like you pay the maintenance and go forward

This way you don't have a 42000 pound boat anchor to try and figure out how to get rid of!! lol

Maybe there is also something of "the devil you know versus the one you don't" to consider in the decision.

hey guys, here with another update, and a bit frustrated, maybe you guys can help me out...

Last year, when my manual transmission had a lot of issues, and after having it worked on multiple times, I bit the bullet to install an automatic. It's been great, except sometimes when we park close to the interstate, it takes about 5 miles to shift to 3rd? I've heard that is somewhat normal...

Well, I had told WW Williams to check this out once they got the motor rebuilt. The motor has now been rebuilt and was test drove today. Motor is doing great! But they mentioned that there was no modulator installed to tell the transmission when to change gears, I guess changes based on air/hydrolics? (I don't know)... but they told me if I didn't have a modulator that I could be looking at transmission damage in the future???

Because I'm supposed to have a warranty with my transmission, I plan on calling the shop on Monday to see why they didn't install a modulator? In the meantime, WW Williams is finding a price on one.

What do you guys think about all of this? Thanks for your input. Blessings!

listen to Williams...

the missing modulator is the fault of the installer, not the rebuilder/vendor...

are modulators easy to find? hard to put on? expensive?

What transmission do you have?

730

If this is it, looks like bargain to me. I'm only familiar with the 643.

thanks Opus!

Better have someone confirm that first. I was looking to see if it was the same as mine....and found that.

That is not the modulator the modulator mounts outside the transmission either cable controlled or air controlled google Williams Transmission modulator the air controlled model will pop up

So would it be this?: http://www.finditparts.com/products/563110/williams-valves-117830?srcid=CHL01SCL010-Npla-Dmdt-Gusa-Svbr-Mmuu-K563110&gclid=CjwKEAjwgqWvBRC2kajZjqeOn0oSJADqBi-lMHYDjXxD2QubwhdNQRvC2cd48QBIk6JSP-I66rU5shoCWJjw_wcB

Thats what I have on my 643.

luvrbus · September 04, 2015, 05:58:57 PM

That is the modulator for a Allison with a Williams air throttle goes on the out side held in by a clip and 5/16 bolt has a air line from a tee from the throttle

If he doesn't have a air throttle he needs the cable operated type from the throttle, push or pull type what ever will work for him lol if I could post photos here I could show you one,Google for Morse transmission modulators (310821) it will pop up with the cable the one to use with out the Williams throttle
