2014 Silverado transmission. Help!!!

[Missphd]

I have a 2014 Silverado that drives like a dream. I’ve always babies it as well as kept my maintenance up. About a month ago I noticed this odd hesitation like it was misfiring when I accelerate after a stop. Then just 2 weeks ago it started making a weird noise when it did that and also the rpms would jump up. These episodes were only a second or 2 long and didn’t even do it everytime I drove it. Then about 4 days ago I got in the truck to leave and it made a crazy noise and then just stopped going into gear all together. I had to put in the manual position and jump bump in 3 sec intervals in the 4th gear. Also had to in reverse just to get home. Also when it was doing those weird episodes, the truck would vibrate like I ran over those strips on the highway shoulder. I hooked to the monitor and it shows the PO700 and PO722 codes. Please help on what to do or what is wrong. I can’t afford new tranny. Thank u!!

Could be as simple as a bad shift solenoid ... or, needing a whole valve body, or TCM. Impossible to say over the net. At the very least you'll need a bi-directional scan tool to command shift solenoids on and off, and look at the results of each command, and understand what they mean.

 

Your best bet if you're not mechanically inclined, or own a $1,800+ scan tool,  is to find a local shop (DO NOT go to the dealer for this!!!) capable of handling this diagnosis and repair, preferably a shop that specializes in transmission work.

 

More fallout from GM's parts cheapout strategy for the 21st Century ...

Would the same advice hold true for a 1995 k2500 in limp mode half the time. Still chasing the possibility I may find and fix the old bird w/115000 miles. I love my ole vrolet.

No limp mode on a '95.  Totally different animal - that's OBD-I, while anything 1996 and newer is OBD-II.

 

Hold on to that truck! They don't build them anywhere near the build quality of those. It might not be as powerful, fuel efficient, or comfortable rolling down the road, but it will outlast ANY truck built after the 2006 model year by a factor of THREE to one - no joke!! Whatever money you have to invest in it to keep it going is money well spent.
