Intermittently feels stuck in gear, possibly bad torque converter

Purchased October 23 and every so often when I start the vehicle and take off it feels like I'm stuck in 2nd or 3rd gear. It moves when I'm on the gas but it struggles, rpms aren't revving high, parking brake is off, calipers aren't dragging but once I start to pull forward it's like I'm being held back, once I stop and I give it a second I can feel it shift down and it's perfectly fine after. I've also noticed that when I come to a stop light, foot on the brake waiting for the light to change every so often I'll feel it shift down, like a small clunk. I do feel the u joints need to be replaced but I highly doubt this is causing my issue. After some searching the only thing I can come up with is maybe a bad torque converter.. Any ideas??

 

The first thing you should do is check the tranny fluid level at the proper temp. Rule that out first.

 

How many miles? Service history?

 

It would be nice if it wasn't a sealed trans, can't get to it until Monday. Buddy has a lift in his garage so it would be easier than laying on my cold cement in the garage.

 

208k service history is nearly perfect. Original owner had taken it to the dealer for every service call up until 200k. I do however see the transmission hasn't been checked since 09 and will be doing that Monday myself. I've never inspected a sealed transmission, but I guess now is the time to learn lol

 

This will show you how to properly jump the obd and get into temp check mode. Also utube has some videos.
Practice this procedure before you do anything.
