88GMCtruck's NV4500 Swap

[94Sierra4x4]

It's ok. If your going to want one for a driver, I'd get the later 95+ with the higher gearing. The low gearing in this transmission has some pretty big jumps between ratios and is much more suited towards pulling loads than driving.

Roger that, I think I'd go with the new style for sure if my plan was to daily it. She'll be more of a toy before too long and I think I may assign the green truck as daily driver..build the black truck into the 4x4 it desires to be. I assume the Low gear would be awesome offroad.

thanks Dave

That is an understatement. The crawl ratio of this transmission, plus the NP241 is insane. I can walk faster in low range.

Cruise control & a stick. Did you get this to work? Did the factory offer this? Often wondered if this was possible with a stickshift.
I would like to add this to my '97. Without ever seeing this in a GMT400, I'm guessing that the cruise only works in 5th.
Does this work the same as an auto where tapping the brakes turns it off? Or is it cancelled by stepping on the clutch peddle? I know that with an auto, if you pop the trans into neutral while on cruise control, the engine will freely rev up to the limiter. (oops!) With that being the case, if, while on cruise, it would be necessary to cancel the cruise before downshifting with a stickshift. (It's just a 6, so shift happens!) To me, the cancelling feature of the cruise would make more sense to be associated to the clutch pedal, as opposed to the brake pedal. My feet do enough dancing on the pedals, without having the need for one more step to the brake pedal to kill the cruise before downshifting.
The cruise control on my '98 is one of my most used & favourite features of the truck. It provides more consistant mileage, & fewer tickets. I really do miss not having it on the '97.

Yup it's 100% factory. It works in any gear, and deactivates with clutch or brake.

My 96 3/4 ton with the nv4500 had cruise

 

[glfirefighter144]

yep, both my 96 with the NV3500 and the Dually with the NV4500 both shut off cruise with clutch or brake too

Wow! Never knew, or even thought to check vehicles in the wreckers for this option.
Thanks for the info!
But damn!!! This forum! You guys! The info & knowledge! = More money to be spent! The longer 'to-do' list!!!
Thanks! I think...
Lol!

Clutch Pedal Bracket

I too am needing this item. I pulled all my pedals at the JY yesterday but could not figure out how to remove this without a grinder or something, which would need to be battery operated of course.

How did you remove this from the donor truck?

 

[88GMCtruck]

I didn't. The one you see there came from GM as a part, which after the big gov't bailout has been discontinued and is no longer available.

 

[4thesporty]

OK thanks.

I guess a cutting disk and stone attatchment for my drill is the answer then.
