Hey. I’ve been having an issue with my Saturn L200 2.2L shifting from overdrive to drive at constant speeds the past couple of days. Doesn’t matter how fast I should add. You can feel it downshifting and shifting back and watch the tach and see it fluctuate. It also seems to have a shifting pattern from a sloppy shift to a more solid shift like it should at times as well. I’m not exactly sure how a Saturn is supposed to shift or what’s normal for these. I haven’t driven one until I got one in Feb of this year but I have driven a Lexus once last year and it shifted sloppy like mine is at times. I’ve seen suggestions that it may be a valve body issue. The fluid is a little dark but not as bad as my Escort was last Sept when I changed the filter and fluid. I ended up putting a trans in that one. The fluid change and new pump valve and spring didn’t help the shift problem with that. Lucky I got $1800 for it when I decided that 5 years with it was enough. Anyway we’re not talking about that now. Any suggestions on what to look into ? No check engine light either. It has had some hesitation on acceleration too, which may suggest an 02 sensor issue but if there’s no CE light it doesn’t add up. The CE light comes on when you turn on the key, so it’s working. Should I scan for codes anyway ? Thanks for any advise.

This is the DOHC engine, correct? How many miles are on this vehicle? What is the condition of the fluid (color and odor)?
This should help get you started
http://www.ericthecarguy.com/faq/solving-transmission-problems?start=3#AutomaticTransmissionsHesitation upon acceleration can be due to a couple things but if it hasn’t had a “tune up” (new plugs, wires, air and fuel filter) lately, I’d start there.

http://www.ericthecarguy.com/faq/solving-automotive-performance-issues%5B/quote%5DSorry to start a new thread on a prior discussion but I must have done the incorrect search for this. I always try and do that before starting a new one. It has 155,000 (Hiway Miles) and the engine is a DOHC. As stated above in my post the fluid is slightly darker than it should be and smells O.K. On a note: There are no plug wires on this engine. I know you were just stating that, if so. I’m going to read these over and I’ll see what I can do from there. Thanks for the links.[quote]On a note: There are no plug wires on this engine. I know you were just stating that, if so. I’m going to read these over and I’ll see what I can do from there.

Ok, that has the coil on plug (COP) ignition which unfortunately can make it a somewhat costly tune up.
Why ? Today that’s about all there is to a tune-up that I know of but I come from the 50’s, 60’s and 70’s vehicle tune-up days when a lot more was involved to a standard TU. Thanks for your comment tho.
This actually makes this the incorrect forum for this but are you saying that line of 4 boots in the bar that screws into the top of the cylinder head can need replacing as well ? Or whatever the technical name for that is.That would be why I’m not understanding the “Costly Issue”. That would make more sense if so.
Correct. Older cars had one ignition coil and a distributor, or a block of electronically controlled coils (called a coil pack), and then a suppressor cable (spark plug wire) connected between the distributor or coil pack and each spark plug. Newer designs such as yours use individual coils that mount directly onto the spark plug. These are called “coil over plug” designs, and are much more expensive to replace.
My ’02 Saturn LW300 has the COP design. When I priced the parts last year, it was going to cost me approximately $150.00 for everything I needed to complete change out of the plugs/coils.
My ’97 Saturn SC2, which only costed $40.00 for plugs and wires, there is a significant difference for that simple job.
Compare that to the plugs wires and distributor cap of my ’78 Camaro back in ’86, ’87, ’88 when I did it back then…I want to say 10.00-15 bucks back then? well there is no way to easily compare then versus now.
