Engine/Transmission (1994 - 1998) Pac brake install

[SMalafy]

Can anyone tell me how long would it take to install a pac exhaust brake on my 2001 w/ auto transmission. I was looking at the instructions and it seems doable . But I do not know if I would need an assistant at some time or not as I live alone.
Also page 8 says to shut off the overdrive to the transmission when doing a road test but I do not have a button to turn it off. And another question strikes me is I do not know if I have an aftermarket lockup torque converter. I bought the truck used from a 3rd party and do not know the first user. All I know is the truck was registered in Mississippi and he tow a fifth wheel trailer as the brackets were welded on the frame. I am guessing he had the transmission rebuilt at least 1 time as I bought the truck with 240K on it. I do have a Rev Max valve body

Are saying that you don't have this button (in the photo below) on the end of your transmission shifter? This overdrive lockout switch is stock on a 2001 truck.

I had a 12 valve before this one and the button was on the dash. I never knew they relocated the button on the end of the shifter. 4 years I never knew it was there but then with the price of fuel I did not use the truck that much and hardly ever in the winter so as to not get salt on the truck.

My 1998.5 had an O/D lockout button at the end of the shifter. It stopped shifting into 4th and allowed T/C lockup in 3rd.

That’s the way it’s supposed to work. With OD off, it will lock up in 3rd. It’s simple to take that switch apart and clean the contacts. I posted a thread about it with pics years ago.
