SOURCE: My pontiac 2003 montana will start fine,while driven on the road,the car just stops. three minutes later I starts it up and it rides,go a few miles and does it again. Can you tell me what the problem

The engine in this car is controlled by a computer, whenever a problem like this occurs you must have the electronic engine control computer checked for fault codes as the 1st step in diagnosis and repair of the problem.

Why does my 2006 Pontiac Montana feel like it kicks at 20-40 mph? - insert more words for faster question answering-

sounds like a bad motor or transmission mount try to step on the gas hard and release it quickly while in park do you feel the same thing if you do a motor mount is no good you'll see the engine twisting or raising up on one side the reason why I think its happening at slow speed is the transmission shifts gears and this lets the motor settle back down if not try with no body behind you quick acceleration then wait 5 seconds and hard stop when the car is stopped and you feel a bang from underneath the transmission mount is no good

My 2004 montana shifts into 2nd an 3rd but wont shift into drive and there is no slippage

That is called overdrive. You have an electronically controlled transmission, so you must have the control module checked for codes with a special tool called a scanner.

Transmission Slipping 2003 Pontiac Montana Checked fluid and all seems fine what could be the problem?

There are two possible causes. First is a leaking lip seal causing the system to slip, which the computer sees and it, the computer then increases the pressure to accomodate the slip, causing the bang. The second is a problem with the valve body. Either a binding valve or pressure regulator.

Both of these will require the transmission to be removed to check.

Hope helps.

Tune up

Slipping tranny can be caused by that. Rule of fixing cars is if not sure start cheap. Replace the Filter and fluid. Also it wont hurt to put in Lucas Transmission Additive with the fluid change. Change plug 2 ways if it has motor mounts on top then disconnect them and pull the engine foward. or

No need to rotate engine as I was told that sometimes this causes damage to exhaust link which is flex. First two plugs can be reached by going along the same channel as exhaust pipe from header runs. Last plug remove right side tire and you can reach up by body to change it. This one is blind, but it's possible.
