I just put an 02 4R100 into my 99. The shifter seems a little hesitant and the indicator needle is off. My wife drives this truck a lot and I don't want her jamming it into the wrong gear.
The Shifter cable and bracket that hold the cable onto the tranny are a little different. The bracket mounts lower on the new one and the linkage itself moves about an inch less on the new one as well. My first guess would be to buy the 02 bracket and cable from the wrecking yard. The problem is no one keeps those. They all throw them away. Who know how long it will be until another one comes in and they remember to keep it for me. Even If I do get one, I fear it will still be wrong on the column since it probably moves farther than the new tranny does on the linkage.
I borrowed the bracket off of my buddies 02 so I have a pattern to make my own bracket, but I fear it will still be a little off at the column.
Can I just take the linkage housing off of the 99 and put it on the 02?

You should be able to use the linkage housing from your old tranny.
I'm no expert in automatics by any means, but they should be essentially the same.
Neither the 02 nor the 99 bracket were quite what I needed. Since the shifter lever and cable are meant to have about an inch longer throw, Park to First gear,than the 02 tranny. I spent several hours analyzing exactly how the linkage on the tranny moved in relation to how the shifter cable was moving. I had already adjusted the cable all the way out. I thought I had it all figured out and I bolted it on but the darn thing would not even go into Park. I was so mad, I cut the holes out with a torch which allowed me to slide the bracket forward 3/8 inch. I bolted it all back on and it works perfectly now. Kind of ironic that I spent all that time measuring everything out exactly and in the end it only took the torch.
I ended up using the 99 bracket and drilling/burning a few holes in it. I bolted the plate to the tranny and then the bracket to the plate. I ended up spacing the bracket out about 5/8 from the plate with some nuts and washers for spacing. I drilled another hole in the bracket and plate so I ended up with three bolts holding it all together for a little more strength. I would have included some pictures but we ruined our digital camera in Puerto Vallarta last week.
