This has a 4l60e trans. There is no "passing gear cable" it is all electonic. I would recomed making sure the filter did not fall down into the pan. When you removed the old filter there should have been a fitting on the end of it like the one you installed with the new filter a rubber seal set up that slips onto the snout of the filter. These usualy don't come out when you pull the old filter out you have to remove them with a tool.(a pic will work if you are careful) I have seen this happen before where a person did not remove the old fitting and this allowed the filter to drop into the pan.If you did change the fitting out I would still check to make sure the filter has not dropped. If the filter is ok then you have another problem. There is a switch on the driver side of the trans that the shifter linkage is connected to this may need to be adjusted. It is not hard to adjust but I recomend getting yourself a chilton or haynes manual from a local parts store for about $20 It will be a big help for ya.
Have a great evening.

I have a2009 GMC 2500 HD with 195,000 miles. It seems like the transmission is slipping or it revs real high before it shifts into gear.

check both your fluid levels and the programming for the tranny, if it's electronic. 195K means you should probably look at a fluid swap and possibly any tranny filter

My 1995 GMC 1500 V6 Automatic Transmission will not shift into 3rd gear. I have cleaned the wire plugs and replaced the filter. What could be the problem?

Not sure which filter you are talking about, but you should change the fuel filter if you didn't. I assume your fluid level is good?

I have a 1996 GMC Sierra with an automatic transmission and just recently as i had been driving for about two hours it dropped out of overdrive for about ten minutes or so then re engaged. then i noticed...

The filter has nothing to do with your issues.

Check for a loose or misadjusted brake switch, for the OD issues.

Maybe Electronic,Sensors or Selenoids,on the shift issues.

My tranny wont get a positive shift into drive and does not move forward but has a positive shift in reverse and works. Is it a filter change or rebuild.

Filter should be ok,if this is 4L60E you could have dirty pressure switches pull pan down and look for pieces in pan sounds like reaction drum shell gear broke off.

Hi i have a 1995 gmc jimmy. I had some tranny issues, it was shifting hard into first and overdrive. I change the filter and fluid and all hard shifting was gone. the problem is that have no overdrive now....

Being that after you changed the fluid and filter out and the shifting got easier but you lost a gear that tells me that something is coming apart in your tranny. Transmission fluid is highly detergent so if you put new fluid in a allready failling tranny most of the time the new fluid will wipe the tranny out the rest of the way. If that truck still has the 700R4 or 4L60 tranny you can try turning the car off, with the tranny in park, stomp on the accelerator peddle several times and hopefully that will free up a possible sticking throttle pressure valve. You can also try replacing the lock-up solinoid inside of the pan but that most likely isn't the issue.
