    The catalytic converter has NOTHING to do with the transmission. Its the Shift Solenoid

What causes my 2003 pontiac bonneville to **** when it shifts from 1st gear to 2nd gear. and when it gets warmed up after 20 minutes to 30 minutes driving it acts as if it do not want shift gear or not...

Honestly, it sounds like your transmission is starting to go bad, With the cars I have had that hesitate to switch gears, the transmission went out soon afterwards. Have you made sure to check the fluid levels?

Also, check the level and color of the transmission fluid. It should be red/pink in color without much discoloration in it. And the level should be at the designated line on the dipstick.

2002 pontiac bonneville transmission jerks or bumps when shifting, however not all the time. Can go one or two days without doing it or once it starts if you stop and turn off the engine and start the car...

Had the same exact type of problem. Sometimes the transmission would **** or jump when the car shifted gears and sometimes it would not. Drained the transmission fluid and replaced the filter. Did not fix the problem.

Here is what fixed my problem. I replaced the Mass Air Flow Sensor. It cost about $150.00. From what I was able to find out the mass air flow sensor is tied into the PCM module that tells the car when to shift.

Hope this if helpful.

It stays in 1st gear

sounds like the transmission shifter control module... try shifting manually from 1st to 2nd to 3rd then drive if it works then thats the problem most likely...

Transmission wont go into any gear except reverse my mech said the torque converter sensor is bad how do i change it

NO I think your forward band broke can you manually shift it to low & car moves If so you need trans overhaul. Don't have that mechanic fix your car he is full of it if converter failed or (SENSOR!!) you would also have no reverse

You are right. The transmission filter should be changed every 60,000 miles. While the pan is off for filter change, add one bottle of Lucas Transmission conditioner into the pan. Reinstall pan and refill with Dextron II fluid. Torque converter is OK.

Hard Shift to 2nd Gear/next gear

Your going to have to get your car scaned for codes. Auto Zone can scan it for you for free and tell your what you'll need to fix it.
It sound's like your VSS Sensor (speed sensor) is not working and your ECM is not getting the signal from the transmission to know when to shift the gears.
Becareful not to burn out the transmission till you get it fixed. The sensor it self is not that expansive and to replace it is easy and takes about 30 min to do.
If you get a P0720 or a P0722 code, then it's your speed sensor. It's an esy fix and Auto Zone can give you instrction on how to change it. 
Good luck, it takes about 30 min to change and hope this helps.

Hyundai Santa Fe 2005 won't shift into first gear

Most likely the o-ring seal between the torque converter and the transmission is going bad. Get that transmission rebuilt pronto before serious damage is done! But first, have a mechanic drop the transmission pan and look for signs of a very thin silvery film coating the inside of the pan. If found, then the transmission definitely will have to be rebuilt, and the torque converter will also have to be replaced since embedded metallic particles in the old torque converter will eventually come loose, due to wear of the clutch plates within the torque converter, and eat up the rebuilt transmission. Now, here is the deal once the transmission has been rebuilt:

Change the transmission fluid and filter once a year -- no matter what! If you do this, then you should never have any more problems with the transmission.
