Sounds like the transmission is done. Time for a rebuild/replace.

SOURCE: my truck loses power

In most cases it is the fuel filter. I don't know when it was changed before, but it should be changed at least every 8-10 k miles. Make sure you change the air filter too.

SOURCE: 4l60e slips in 3rd and 4th

There are to many things that can cause this problem, best thing to is go get the ECM scanned for DTC codes at a transmission shop or Auto zone or Parts Source since they scan for free.
The ECM should have DTC code in it's memory on how the transmission is Performing and have the Transmission line tested for Fluid pressure.
Good luck and hope this helps. Oh and also ways check with more then on transmission shop if there tell you that you need a new Transmission,
It could be a simple as the transmission filter falling off causing the lost of transmission fluid pressure. Check the transmission fluid too.

I'm hearing a grinding noise when shifting gears in my 97 nissan pathfinder. It's not a full blown grind but just a slight grinding noise. It does it in reverse 1st 2nd 3rd and just started doin it in 4th....

check and/or change the transmission oil. Clutch problems are noticeable in 1st and reverse but as all the rest are syncro controlled you really do not need to use the clutch to change them. just get the engine rpms to match road speed and they will slip in. I am thinking a oil viscosity problem because of the colder weather.

2007 Chevy Avalanche 3rd and 4th gear are not working

From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!

1st 2nd 3dr 5th and reverse gone MT

If 4th gear is good, no slipping, then your transmisson is toast. Replace with a known good working one.

2007 yukon gears seems striped or transmisson prob. only 72000 mi

It is an internal trans problem. I build transmissions for a GM dealer. It is going to be the input carrier, forward sprag, and 3rd/4th clutches. I have seen several. Get it to your dealer. That truck has a 100,000 mile powertrain warranty. That includes the trans. Good Luck.
