Default No gears with non-tilt column (74 k10 w/ th350)
Recently put a body lift on my truck, now the shifter won't engage the transmission.

Prior to body lift, the shifter engaged everything just fine. Immediately after body lift, only was able to select between P R and N. It would not engage Drive, 2nd or 1st even though the shifter could be rotated til about 4-5 o'clock. Engaged Park, Reverse, and Neutral just fine though.

Assumed it was an issue being that the trans linkage had not been lengthened yet. Proceeded to lengthen it the 2" necessary while ensuring the linkage was clocked the same as factory.

Proceeded to reinstall, still had P R N, no D 2 1.

Figured it may need some adjusting, loosened the linkage at the trans, set both the trans and Steering column in Park, then tightened it back up.

No dice. Now the steering column won't engage any gear. Column won't shift without key in ignition, but selecting a gear doesn't translate to the tab or linkage. Steering column shifter can be set anywhere, and the trans can still be engaged by manually rotating the steering shaft tab to select the gear.


No problem with trans, only with steering column. Guessing the shift tube is busted. Where can I find a new one? Or is it easier to get another column?

Figured it may need some adjusting, loosened the linkage at the trans, set both the trans and Steering column in Park, then tightened it back up.

Try adjusting it again.

This time (after loosening the locking bolt at the transmission end of the linkage) rotate the transmission shift lever fully clockwise to the "P" position and then rotate it CCW two clicks to the neutral detent.

Go up to the column gear shift lever and rotate the lever until you feel it drop into neutral gate notch. Do not use indicator pointer as a reference to position shift lever.

Go back down to the transmission shift lever and tighten the locking bolt.

Appreciate the added info. I'll give it a whirl after class today.

My biggest concern is that the shifter doesn't seem to engage the shift tab:

Seems more and more like its a busted shift tube.

Took the linkage loose at the trans bracket. Was able to go between gears with no issue. Full movement at the linkage tab on the steering column. Set it in neutral, set the trans in neutral by hand, and tightened them both back together. Went to shift through the gears.... no dice. No movement transferred. Dad said it was slightly wiggling when going back and forth through the gears.


Looks like its busted somewhere between the shift lever and the linkage.

Taking a look at the shift tubes that some other trucks use, it appears that there's a key race on the tube that locks the shift tab in sync with the column shifter.

Basic knowledge always states that a part will always fail at the point where all the force and torque is applied, i.e. the key race/shift tab. Is the race cast/machined with the shift tube or is it separately pressed in with the tab slipped over it and held in place via the spring and/or lock nut?

I was wondering how you were coming along with this.

In addition to the keyed interface between the shift tube and the gear shift bowl, there appears to be another - even weaker - group of couplings integral with the shift tube itself:



I don't know how many plastic couplings there are or exactly where they are located, but I took an educated guess and circled possible locations in blue. The red tracers depict the key and keyway:




Parts list for above:
