Hi passing gear is actually your transmision drpping down to second gear.if you hit the gas hard.if you hit the gas lightly it will only drop out of overdrive and go into third and not go into passing gear.

Losing power going up hills

sounds pretty normal. what speed do you try out the passing gear? anything above 35-45 mph and it will feel like neutral. Passing gear is actually only 1st gear. When you press down the pedal, it forces the transmisson to shift into low gear.

1997 GMC 5.0 4x4 won't kick down to passing gear. RPMs rise but truck just lags and doesn't increase in speed

passing gear adjustment needs adjusting--unless qualified--take it to transmission garage. If electronic--the switch may be bad.

Transmission shifting

Bring the vehicle to a transmission repair shop there they will scann the vehicle for codes and do the repairs that the codes list.
By your write up I would like to pressure test the main line pressure before I say anything.
I'm hoping its the shift solenoids.
Good luck

I have a 94 gmc sierra with 350 that has problem shifting to 2nd

Your problem likely resides with the hydraulic valve that operates the band for second gear, or lack of hydraulic pressure in the transmission. If the actuator in the transmission that operates second gear is getting sticky, then it will cause this. A filter change and flush may help, but it's likely time to start looking for someone to tear down your transmission, or replace it.

Tranny will not shift into dr or od

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.

What gear can I start with & which one is the speed gear

almost without exception start in first. this will save your clutch. try to keep your car in the highest gear you can but keep your engine rpms above 1500. if you need to pass you can down shift one gear, pass then get back to top gear. the best way to learn is to drive. every car is diffrent.
