RE: Column Shifter Hard to Move
I posted a similar concern with my 1999 Tahoe a couple of days ago, and think I found the part needed to fix the problem. It's called the 'steering column shift control mechanism', and 1A Auto Parts has 'em for $106.95(aftermarket). Here's the description verbatim from their website:
This replacement Steering Column Shift Control Mechanism is just what you need to get your GM truck or SUV in good working condition again!
It mounts to the steering column on the RH (passenger side) and is what the shift lever attaches to. When the shift lever is moved to any position, P R N D 3 2 1, it moves the inner parts of the steering column, which is attached to the transmission shift linkage. It also has the park, shift lock cable attached to it so that will not allow the shift lever to move unless the key is entered into the key ignition and moved forward. This part is commonly broken when vehicles are stolen. It also is the cause of why some steering columns have a hard time of moving in and out of the park position.
If your steering column is having problems shifting and the cause is because of a bad or malfunctioning shift control mechanism, this is the part for you!
Features:
Attaches to the RH (passenger side) half of the steering column
Brand new component with park, lock cable attached
Replaces dealer part number: 26091246
Built to strict quality control standards
Only fits vehicles with Automatic Transmission (AT) and with a column shift

This Steering Column Shift Control Mechanism is a great replacement part and has good cost savings over the price of a dealer part.
