2000 Pontiac Montana... Turn on... Good. Drive down street... good. Accelerate... Auto transmission jerks or jumps into next gear. Check engine light is on. Autozone told me o2 sensor was bad. Will a bad...
No, O2 Sensor would make your van to be none fuel efficient at least or won't change anything if it's the O2 Sensor or Bank2 ( It mean's the 2nd one, the 2nd one is a dummy.. it just read what's going out from the catalytic converter and tell's the computer if there's a change since the reading of the first 02, so the computer see if or not the catalytic do his job ) For your Jerking and Jumping problem.. those Gm Van has alot of transmission problem and maybe your transmission on a way to take vacancy or it is just missing oil ! Check Oil first, for that do that when the Motor is Cold, Start you Van Leave it in "Park" Position, Pull the Dipstick of your transmission ( Should be the Red one ) clean the end of it with a Rag and put it back, pull it a gain and check if the oil is in the reading, if not add the missing oil while the motor turn's, and recheck it until it's full ! Otherwise if the dipstick show's Full, Here's a tip's go to your local autopart's supplier or store that sell's car product such oil's, coolant ect.. ! Buy a Bottle of : Lucas Transmission Fix, Remove the Transmission Plug, and remove about the half of the oil ( Not the Whole amount of oil, only the half it's important ! ) and put the plug back well tighten, pull the dipstick and add oil from the dipstick tube with your bottle add about the half of the bottle, start your van, check the oil level if it still missing some oil add the amount it require to be full ( While Motor is Turning ) ! Important do not Overfull the transmission ! This Should Work or not, if not.. I would say you need to Replace your Transmission, What I told you is about 15minutes of your time and a couple of dollar ! Best thing is to bring your van to a Transmission Shop they will tell you the problem !
