I have 2, 2004 era K line engines with tmcc both have dual can motors. Run well, too well. By the time I am at 12 of 32 steps, they are ready to fly off the track. The heavier one if it has a few cars can run slow, but the lighter one at step 1 is running too fast to do a coupler connect without derailing everything.
Can I convert these motors in serial to slow them down? Anything I should check for? Is there any other speed adjustment that can be done?

Does one have cruise by any chance? If you have one running cruise, the speed curves will be totally different. Before you go wiring the motors differently, let's identify exactly what you have.
I have a few of the K-Line GG1s from that era... they are definitely supercharged. I think these are around 2001. It is scary how fast they will run!
K2780-4935, K2780-4892RS, K2780-4907

I would think that if the loco has cruise, it would not have this high speed problem.

Nobody said the cruise was working correctly. 
This is K-Line we're talking about!
Here are pictures of the worst offender, a CTR RS3. K-2416-4545 There is a radio, Railsound and RS power board. Also the main power board for the motors. And a smoke unit. The motors are hooked up in parallel currently. There are Prog/Run, SS/RS, Smoke switches and volume control.
A close up of the main power board for the motors.
The right hand plug, Red/black is from the track, Brown/blue go to the motors.
What do I look for as far as momentum or other settings that would prevent wiring the motors in series?
That has a stock DCDR with no cruise capability, wiring the motors in series is possible. I don't know if you'll like the performance, but it'll work fine.

Thank You for the information. I have been digging through the TMCC files on the forum and elsewhere. I am still studying it out. Running in serial may be better for low end, but that effects the top end voltage to the motor also. With grandkids, I may not want fly off the track speed. Testing to continue.
Easy enough to wire one engine in series and see how you like it.
