Engine/Transmission (1994 - 1998) More pedal resistance on the 'loud pedal' please

[VicR]

Kind of a strange question: My wife really likes commuting in the 97 and loves the auto transmission in traffic, but her only complaint is that when the truck shifts to overdrive, the resistance on the 'gas' pedal goes to almost nothing. It has normal resistance in 1-3, but as soon as it hits OD, it only needs a feather weight to go. Any ideas?



Thanks,

Stiffer spring

You have two springs attached to the throttle linkage, one may be broken. If they are both intact get a spring that is part of the Jacobs e-brake package Cummins part # 3933131, Jacobs part # 024019. Try to find a stool next to the parts counter when you order it so you can be sitting when they give you the bill.

Foot pressure is such a relative thing it's hard to judge. Do you notice the difference yourself? Might just be her perception. Is she used to driving the truck? Diesels have a different feel than gas engines. I know my wife's Blazer is totally gutless after I drive my truck.



One thing you should check as far as pedal resistance is the TV cable that runs to the transmission. Make sure it is not binding. When the throttle is closed, the lever on the transmission should be fully at rest. When the throttle is wide open, the lever should be fully pulled.



Good luck.

I can give you one or two heavy throttle return springs if you want.

Drove 'her' truck to work today and I see what she is saying. The pedal has normal resistance in 1st, 2nd, and 3rd, but when it hits OD, the pedal takes only a fraction of the effort to push it that it does in the first 3 gears. I can't see how the shift to OD would impact pedal pressure, but I'm sure there is a simple explanation. I played with it a little tonight, but it was dark so I couldn't get much done. I could only find one spring, so that might be part of the problem.

Vic, I've been thinking about this awhile. When my truck locks up in overdrive I have to let off the throttle to keep the speed the same as the truck wants to pull ahead faster - in fact very very little throttle pressure is needed to maintain speed. These engines have so much torque they will pull really hard in OD with the clutch locked up. Maybe that is what your wife is seeing and she's not used to the feeling. Just an idea.

Do you have a pressure lock from BD on it? If so, an adjustment need to be made by stretching the spring on the pressure lock.
