SOURCE: saturn shifter linkage

The bushings on ebay work from what I understand, but a bit pricey. The bushing in question is a P.O.S. for sure. Easy fix though if you have tools and time. First I drilled out the ball that the end of the linkage,the one your faithfull broken bushing use to ride on. popped a 3/8 inch bolt thru the drilled hole, put a piece of 3/8 inch heater hose "cut to length desired" over the bolt ( this is what the linkage ring rides on ) put a rubber gromet or rubber washer that has a hole big enough to fit over the heater hose on each side of the linkage ring ( oh and dont forget the lube - regular grease will eat rubber so use good judgement). put a washer big enough to keep your gromet or rubber washer from falling off, and then a lock nut, and I cannot stress the fact that it has to be a lock nut. DO NOT tighten the living **** out of everything, that little linkage ring is plastic after all just tighten it "lightly snugish" and just make sure your lock nut can't be un-tightened by hand. I hope all of this makes sense, anyway total repair cost- one hour of my time, about $4 of parts at the local auto parts store. best of all, it should outlast the car. Oh fyi, I used rubber parts because that is less likely to break the plastic linkage ring. Showed what I did to a mechanic in town, said now he actually knows what to do next time one of those f-ing saturns comes in with busted linkage. Good luck fellow "manual" saturn owners!

It could be any of the sensors. Take it to any auto parts store that runs the diagnostic computer on it for free and do that. More than likely it will be one of those sensors. I had a oldsmobile that i had them check and it ended up being the MAF sensor. there are many sensors connected with the service engine light.

SOURCE: bleed the clutch

No way to bleed the clutch system.You need to buy a clutch master/Slave assy from saturn.Comes completely full of fluid & ready to install.It has retainers to hold slave pin in place until fully installed.Once installed you push the pedal & you will hear a faint click which is the slave retainer breakaways relieving.No other way to bleed although aftermarket parts house will sell you individual pieces.hope this helps

SOURCE: P0741 Torque Converter Clutch Circuit Performance

it's either the tcc solenoid inside the valve body not engaging or the converter itself is on it's way out probably due to bad seal.. change that also if you go the converter route..check also the ground to the solenoid and make sure it's getting enough voltage. make sure the fluid is up to date and flushed before all of the above. and remember after solenoid install car wont drive right for a few miles until computer picks up new solenoid or get new transmission installed

SOURCE: 2002 Saturn SL1 check engine light code P0303

For old models, Saturn/GM also used the same material fiberglass gasket in your model, you almost certainly have a leak from a crumpled, sucked-in gasket as I suffered (and many others). I would say going to Saturn dealership to make repairs is probably not good idea if they are going to put in the same GM intake gasket part. Maybe possible to specify Felpro gasket with whatever shop you go to if you don't do the repair yourself. I would not go too long with your car in that condition as there is localized leaning at your cyl-3, that could cause a burnt exhaust valve there.

The exhaust is extra hot venting out that cylinder. P0303 is misfire at cyl-3. Mine was P0301 (cyl-1). You may get P0507 once in a while when PCM fails to control the fast idle caused by the leak under certain conditions. Most of the time, it is very slow idle caused by 3 cylinders running. You run smoother in cold idle because the IAC opens up to increase idle and end up lowering the manifold vacuum, so the reduced vacuum causes less leaking at the failing intake manifold gasket.

I'd say try cleaning everything with your ignition before replacement; Idle problems could be caused by engine coolant sensor (ECTS). Are you sure it was changed? Did they put on a new wire connector along with it?

Hope helps.

Where is the clutch solenoid on montecarlos 2000

This code refers to the electrical side of the torque converter not the inside workings of the converter itself. Check the electrical connector and harness for opens breaks or chaffing. Most of the times the tcc solenoid replacement will fix this issue.

I have a 2000 Chevy venture and recently about 6 months ago had the transmission overhauled and now I have code p0742 showing up. Could it be replacing the water pump and fuel pump be causing the code...

Hello: P0742 MEANS THE TORQUE converter clutch is stuck on. The repairs on the water pump and fuel pump should not have caused this. The P0742 could be caused by electrical connection going into the transmission, a dirty/failed torque converter solenoid, debris in the transmission. Recommend you get code cleared at Auto Zone, O'Riely, Advance Auto (they probably won't charge you) and see if code comes back, it may only be a one time incident. If it comes back then it will need to be repaired. How long is the warranty on the trans overhaul, time? miles?

2001 Pontiac Bonneville engine code: P0742 Torque Converter Clutch Circuit stuck on. How do I fix this?

Well you have to take transmission's valve body cover off and locate the torque converter clutch solenoid and take it off and change it if necessary. because without that solenoid your transmission will not survive for long. Good luck

CODE P0742

P0742: torque converter clutch stuck on. You didn't say what your cars symptoms were but it should be a low idle, stalling, or a vibration when you come to a stop. In any case you will probably want to send the car in for a check-up and go from there.
