SOURCE: 99 Chevy Malibu - auto trans - no dipstick

You have what is called a closed cased transmission. You have to crawl underneathe to get to the tranny and remove the upper bolt close to the side of the case (more towards the bottom of the transmission). When you fill it, you fill it till it starts to drip out of that hole.

Looking for a picture for you.

SOURCE: can I clean my Maf sensor and throttle body myself

Yes it will help car run better. Take off any hose that goes to card so that you can see down throttle bore. Start car. Grab throttle linkage and figure out how to move it so that you can make the engine go faster. Begine to spray inside throttle body using little red hose that came with carb cleaner. While you are spraying the engine will try to cut out move the throttle linkage to speed up the engine so it won't cut out. Keep spraying all around inside and outside throttle bore.

My 2006 chevy malibu doesn't want to shift gears codes P0121 & P0101 & P0420 transmission place said it's not the transmission.


P0101....Mass or Volume Air Flow Circuit Range/Performance Problem
P0121 - Throttle Position Sensor/Switch A Circuit Range/Performance Problem.
P0420 - Catalyst System Low Efficiency
there is criteria that enable trans shift
solve codes problems then transmission will shift normaly

How do I change the throttle position sensor in my 1999 chevy mailbu?


Disconnect negative battery cable. Remove intake tube from throttle body. Locate tps, unplug it, remove the 2 screws holding it on and take it off. Make sure throttle is closed and install new sensor. These screw strip out easy so start them with your fingers then tighten them. Plug it back in, install intake tube, and connect battery and your good to go. Also this would be a good time for a pm on the throttle. Get some intake cleaner and a tooth brush and clean any dirt out of the throttle body. Good Luck.

the ( iac ) idle air control needs cleaned. it is mounted on throttle body to control idle speed, remove the torx screws holding it on. do not put body of valve in any liquid or it will ruin it. clean valve on end with carb, or throttle body cleaner. use a old tooth brush to clean it, or similar. this should do the trick if it is not bad!! also check wiring to it for broken wires etc. have a good day !! do not push on valve or it will mess up setting. proper setting is 1 and 1/8 from tip of valve to body of iac. hope this helps.

My '99 Malibu is shifting hard when it starts to get warm. I've taken to a tranny shop and they couldn't find anything wrong. someone mentioned about the motor mounts? how serious is this? and will it...


the shift linkage to transmission may be out of adjustment. on the chevy malibus the tps ( throttle position sensor ) has a big effect on how tranny shifts. check tps first. it is on side of throttle body, at the throttle plate.

Dtc code p0121 and p2135 2007 chevy malibu


both codes refer to the throttle position sensor, the sensor is at the throttle plate, on the side of the throttle body. to test remove the connector to sensor, use a ohms meter to test. put 1 lead to top connection and the other to the bottom one. move throttle and the needles on the ohms meter should move very even, move throttle slow to get a good reading, needle should move without no hesitation, if the test is bad replace tps sensor. if the sensor gets to bad, it can have an effect on transmission shifting. after fixing sensor have the light turned of with an obd2 scanner.

99 RX300 Engine code keeps coming up lean


Check for vacuum leaks. ie, vacuum lines them selves, the rubber tube that runs from the air filter to the throttle body. If it has a plastic intake manifold, possibly the rubber port seal gaskets between it and the engine. Lean codes are set when the PCM isn't monitoring all the air coming into the engine (vac leak) or low fuel pressure.

Suspect 99 malibu broken timing belt


If its a 99 4 cyl 2.4 ltr it should have a timing chain. Check your PCV (positive Crankcase Ventilation) Valve. it should rattle when you shake it. sometimes you can clean it with carb cleaner. but for what they cost, just go buy a new one. When they plug up it doesn't let your crankcase breathe and you will start getting oil in your throttle body or carb. Gas engines don't like to run on oil for the combustion process.4 cyl engines dont have a pcv valve just the v6 motor...

99 Chevy truck check engine light running lean on fuel


Sounds like a vacuum leak. try spraying carburetor cleaner or starter fluid around vacuum lines and intake while engine is running if you have a leak engine will speed up when cleaner hits leak.
