About Carl Brandt
Expertise
Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor.
I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.
Experience
Experience in the area
40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 3 1/2" suspension lift. This gives me a total lift of 9" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a K&N air filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 95:1 in low gear/low range.
Other vehicles I own, are a 95 Ford F-250 with a 6" lift, posi rear end, 35" MT's, 5 speed with a fuel injected 460 ci engine, and a stock 2000 Grand Cherokee.
Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.

You are here: Experts > Autos > 4-Wheel Drive/SUVs > 4 Wheel Drive/SUVs > f-150 shift from park
Expert: Carl Brandt
Date: 8/4/2007
Subject: f-150 shift from park
Question
My 94 F-150 started not shifting from park until it has run for a couple of moments. I understand that there is a brake circuit interlock. I had blown a fuse a few years back and it wouldn't shift until the fuse was replaced. My wife watched for the brake lights which did not come on for a moment. Once they lit, it would shift from park so it's not a fuse.
Answer
Ken,
I would replace the fuse anyway. You may have a bad or dirty connection in the fuse block. The next thing you should check is the brake light switch itself. It may be hanging up, or failing.
I would guess that the problem is the brake light switch due to the brake lights taking a little time to come on. They should light up as soon as you touch the brake pedal.
