Hi!! I'm new to the forum and I'm looking for an Allison tech. I have a 4500 and I need to replace the ps1 switch. Any info would be greatly appreciated.

Welcome

We did have one person, quite a while ago now, but he is no longer participating here. Perhaps another one of our members will be able to help.

Thanks Stu, hopefully a tech will see it.

"The Allison man" use to be on several boards but has not made an appearance for quite a while. The last I have seen him was on the FMCA board but has been some time ago.>>>Dan  (the Allison man" is a retired Allison engineer, responsible for the development of the new synthetic fluid formula for Allison)

Thanks for the input. I think I stumbled my way though it. Pressure switch is bad. Thanks again for the help
