loss 3rd gear/no power in 3rd gear, p0700

So I was driving home last night and about a mile from home, I realized that pretty much had no more 3rd gear, and a cel popped up. This happened after I had to pass up like three people doing 40 on a 60mph road. Weather was somewhat cold, maybe 40-50 degrees and engine/trans were fully warmed up. This jeep has never liked cold weather, especially when driving before it's been warmed up.

But I went back to test it today and it's still doing the same thing. Put it into D and go driving, it shifts from 1st to 2nd just fine. but right as it comes to 3rd, I don't feel it shift, what happens is right when it's about to shift into 3rd, the rpm's jump up from 2k, to maybe 4k under a light peddle. And there is no power, press the gas and it just revs higher like you're in P or N.

I don't think I've loss 3rd gear completely. Reason I say this is because When i'm in D, and the engine is reving high like it's in 3rd, I can still manually drop in into 2nd by shifting the selector out of drive and into 2nd. So i think I am in 3rd, just there is no power. There is also a noticeable buzzing sound coming from somewhere around the trans, like a bad solenoid pack or something, Threw a code P0700 which i believe is just general transmission error, but wjjeeps says speed sensors could be a cause.

Has anybody had an issue like this? I did put a shift kit in a few months ago, but i've had no problems with it. Fluid level is correct and it still looks fresh. No burnt smell.

Not sure if it's a similar problem or not, but I lost overdrive due to a bad speed sensor. It was about $18, one screw and a wiring clip. However, in my case, I did not lose power. It just ran around 3,500 RPM's. I did some quick digging and came up with the following video. It sounds like what you are describing.

Good luck!

You need to get codes read by better code reader. 700 is a code, which means "there is a transmission code". Cheap readers don't see transmission code, they just show 700
