Removal of the CAT will not make your truck go into limp mode, but it will effect your fuel mileage.
Getting rid of the cat converter is the worst idea that has been put into your head
It is there for a purpose , improves economy, doesn't restrict performance and if removed places you in a position for an unauthorized modification that can cost a lost of cash
and yes it can put the engine in limp mode as it affects the engine sensors and that affects the air/fuel settings
And yes problem in transmissions will put the engine in limp mode as the program is to protect a failing transmission as well as an engine

most newer vehicles have transmission control modules,that go to a default of 2nd or 3rd gear when they go bad! I had a 91 plymouth stuck in 3rd gear because of this module! could be your problem! when mine went out, it smelled like something electrical burned inside the the passenger cabin! I would check all the electrical connections on the transmission first good luck

Hi Virtgen
If you have checked your automatic transmission fluid, and its OK.
Does it smell burnt ?
Sounds like you have a mechanical problem in the transmission.
The ABS light on is another problem.
This is usually associated with a rear ABS sensor faulty, due to corrosion in the rear hub.
Give me some feed back !

There are some sensors on the transmission that tend to go bad. You may also need to check the wiring. Could be a computer problem. How many miles?
