I have a 96' Deville, I had experienced some problems with rough shifting, but not bad at all so I had the car serviced they put a new transmission kit on changed the fluid. When I leave the shop my light is still on and my car will not shift into overdrive. Any ideals?

My last log was about the trans sensors. Well I got that fixed. But millage is still off. But my main Q tonight is The service light has come back on says Service Emission system??Filters are fine. I have codes P0325 KNOCK SENSOR 1 (BANK1. P0401- EGR Flow Insufficient detected P1406- Unknown We had the knock sensor replaced a bout 2 years ago so I don't look for that to be the prob..... unless that is a re-accuring thing with these cars....Plus now in climate control will not function on AUTO only ECON. .....anddddddddddd sometimes it just shuts off for a few minutes and comes back on(the heat or air). So with all this what my next best move?? Rebecca....

Replying to: jaymej (Dec 19, 2007 6:02 pm) I am guessing they just pulled the pan, which takes 'some' of the tranny fluid out, and put a new gasket on it and buckled it back up. And this didn't do anything to help your problem. You've probably got a shift solonid problem. There are three of these. Two of them can be replaced rather easily. The transmission does have to be opened up, but they can be accessed from the bottomof the car. The third one is buried deep within the tranny, and the motor and tranny must be pulled to get to it. This one usually sets a 0741 error code. You need to have the error codes pulled, and someone interpret them correctly. If it is a code for the 'A' or 'B' shift solonids, you are lucky. If a 741, it is going to cost a lot because of the labor to pull the tranny. Unfortunately, not shifting into overdrive sounds more like the 'expensive' one. |

Having a few problems with my caddy. Rough idle, surging at 30 to35 mph then smooths out. Have been told that it might be the electronic throttle positioner. This vehicle only has 96,000 miles on it an is in show room condition. I've changed the plugs,wires,cap,rotor. Also the catyletic convertor changed out,all the filters,except the fuel filter. only run premium fuel in it. It has The 4.9 V-8 engine in it. Some please help me in this matter. I'm stumped and almost ready to take it and have a diagnostic ran. There is no service engine light on or anything telling me if anything is wrong. Can it be the E CM has gone faulty?

Replying to: toneyg (Dec 31, 2007 2:47 pm) If so, there are 2 air passages in the bottom of the intake that clog with carbon and cause dirveability problems such as you are having. These passages can be seen by looking straight down into the throttle body. Use a probe or screwdriver to clean these passages and your problems might go away. Otherwise, yes, the idle control and/or throttle position control (some cars have both of these) can go bad and cause problems. I'm not sure these type problems would continue until 30/35mph. If these are the problem/s, I think replacement is rather simple, take off the old ones, put on new ones. BUT, getting them re-set so they work well is a real mess, best left to a mechanic who understands them, or has factory service manual to follow the procedures. There is also MAP sensor could be bad or the Exhaust Gas Recirculation (EGR) valve that could be also clogged or bad. Finding a mechanic with experience on this age Cadillac might be your best bet to narrow down exactly is your problem. Or, if you was to pursue it yourself, buy the factory service manual, not one of the after market ones.
