#80 of 133 Re: Bad Transmission [niso30091] and Code 42 [wzbzjmn] by masterson89 Aug 05, 2008 (1:29 pm)
Replying to: wzbzjmn (Jun 11, 2008 3:50 am) if your cat needs to be replaced because it's rattling there is a good possibilty that your exhaust has excessive back pressure, which is hard to diagnose without running a back pressure test. your exhaust my seem fine, by listening and feeling but without doing a back pressure test u won't know. u should be n the area of around 2-6 psi backpressure much more than that will cause stalling and hesitation . if u have no access to back pressure testers you can remove your o2 sensor in front of the cat to let the exhaust escape or unbolt ur exhaust at the manafold. it'll be loud but if it runs better that was ur problem. also back pressure will cause the computer to belive that your other sensors mey be feeding fals info when really there fine, such as throttle position sensors, M.A.P. , M.A.S. O2. this will in turn cause erratic shifting of your tranny and also a huge loss of power and fuel economy. now after this is determind, u still have to know what caused your cat to be fried n the first place. don't replace it untill u fix the problem or u'll fry your new one .check out that EST problem that can casue rich fuel mixtures that will fry ur cat. also engine coolant will fry a cat in minutes. if you have had head gasket problems of allowed coolant into your combustion chamber that may have been your problem.never diagnose a bad tranny untill your engine is running good. hope i helped. good luck Replies to this message: luminaguy93 (Aug 12, 2008 7:44 am)
#81 of 133 94 lumina euro radiator fill procedure by mattchuu Aug 11, 2008 (7:56 pm)
at a gas station my bottom radiator hose got a hole so i replaced it and filled the radiator back up with coolant. there was a sticker in the engine compartment saying that there is a certain way to fill the radiator back up it said to refer to my owners manual for instructions. but it didn't give me a procedure to follow just info about how to mix the coolant and water. so i just filled it normally and now the low coolant light keeps coming on but radiator is full and the over flow tank is full. so dose anyone know the proper procedure?

Replying to: mattchuu (Aug 11, 2008 7:56 pm) It is possable that the sencer is bad that tells the computer that you are low, another think may be there is a bubble around the sencer, my low coolent light recently came on and i checked my coolent lvls and they were full so i started it back up and drove down a really bumpy road and about 5 minuets later the light turned off, try that first and then check the sencer.
#84 of 133 lumina transmission problems by brian78 Aug 18, 2008 (4:46 pm)
My 2000 chevy lumina with 151400 miles jerks when shifted in to gear. It also jerks hard when shifting 1/2 the time through all gears. I can hear it whine most of the time as well. I have just bought the car from a dealer "as is" and they wont help me at all. What is the problem? And do I need it fixed imedently? The problem is no worse or better than when I bought it about 1000 miles ago.

#86 of 133 Car cutting of while driving by tagregory Aug 29, 2008 (5:28 pm)
I have a 1999 Chevy Lumina with over 200,000 miles. It will cut off while I am driving. The word VOLTS and picture of oil can will light up. Sometimes I will feel the car jerk so I will ease off of the gas pedal and it won't cut off. The fuel line was repaired about a month ago and the mechanic recommended replacing spark plugs and wiring. Any ideas as to what the problem could be? Thanks.

Replying to: brian78 (Aug 18, 2008 4:49 pm) I have a 2000 Lumina. It also will whine at times and jerk when shifting. It is related to the transmission. Check the level of fluid. I have put an additive in the transmission fluid which thickens the fluid. It has helped my Lumina. It could be more trouble in your case but I chose the least expensive treatment first.

Leaking coolant from right hand side of motor(belt side) close to bottom of motor where all the pulleys bolt onto block appears to be some gasket top to bottom of the motor and my leak is near where the oilpan bolts to block, any ideas what this gasket is called, the water pump and Ac appears to be bolted to this plate.   hjc
