Hello everyone, I am new to the site. I have spent hours looking at old posts and while theyre all very helpful, I still havent seen what my problem is.
 
A little history: Its a 2000 GX, It has about 145,000 miles on it. I've replaced the radiator, water pump (twice), reservoir tank, Mass airflow sensor, wheel and hub assembly and other random stuff.
 
While driving (stop and go) when coming to a stop I'd swear that my car is gonna stall but it (always) catches itself and brings the RPMs back up. Then upon taking off again there is violent jerking. I am positive its the torque converter, but I am having so many problems and I have taken it everywhere from autozone to GM. I was told that my torque converter is stuck "open?" or on.
 
I have intentions on getting my transmission replaced (rebuilt) , I will be getting the final verdict on it soon.
 
I love this car and have no plans on abandoning it, even though my camry ran like a dream it just didnt have the umph to get into traffic. Any input would help.
 
A few other questions....
 
are the spark plugs a pain to replace? and how long should a spark plug cycle last?
 
and why is it so common for my car to burn through like a quart of oil a month or so?
 
I do not have a manual, but reading around i have seen that there is something that controls my idle and sometimes can get gunked up? (like an air intake thing).
 
Thank you all for your time, and im looking forward to any reply.

The common problem with the torque converters in these cars are normally 3rd to 4th gear shift after acceleration. I haven't heard of the torque converter causing a near stall while braking. Are you having any other issues with shifting while driving? I've read many people swear by Lucas oil treatment for transmissions and have had luck with this helping the torque converter. Before doing a rebuild, try replacing the transmission fluid and adding a bottle of Lucas transmission treatment. Never tried it but some people have had luck with it.
 
Do you have any "check engine" lights on? If so, get the car scanned and post the codes.
 
The front spark plugs are easy to change, the rear 3 are PITA. Others have reported needing an extended socket wrench. some have reported removing the engine mounts and "tilting" the engine to give more clearance. I took a quick look and saw this was too much for me to handle and had my mechanic replace my spark plugs. He commented they were tough to reach and the bill reflected as much. the spark plugs are 100k plugs.
 
The 3.5L engine is derived from the 4.0L Northstar engine (also used in the Aurora). This engine burns oil. i was burning about a quart every 1500-2000 miles. There are many discussion about this on the internet. Most are too detailed for interests but no one has found a solution.

Well I have been "manual" shifting, but yes, between 3rd and 4th it is terrible. Yes I do have a check engine light on, and when i took it to be checked, the very condescending autozone employee was only too eager to say "its your torque converter" and couldnt offer any information on what to do. I took it to an independent shop who drove it and said that it was the tranny and they didnt touch them. So I'm kind of stuck, I wish i would have asked him the exact code but im fairly certain that its the P0742, by what he told me.
 
This is sheer ignorance talking, but would a transmission problem make a check engine light come on?
 
Yeah, I was never too worried about the oil consumption after reading a few posts.
I just had no idea if it was a design flaw.
 
At the moment, I am thinking the worst, and if thats the case then I'll need a rebuild.
 
I will get the car scanned asap, and Ill post the exact codes. Thank You.

I would find a good transmission shop and have the torque converter replaced based on the independent shops diagnosis. Ask the indy shop if they can recommend a place.
 
here's a discussion on the P0742 code: http://townhall-talk.edmunds.com/direct/view/.f0fecb3/12

Intrigue transmission -p0742, p1811 by zenfm

I own a 99 Intrigue that has recently reached 100,000mi. During the last month, the transmission started to shift roughly but only intermittently. It has since ran smoothly and I don't perceive any slippage. I went to a GM dealer who scanned the car and came out (after an hour) with the above codes. I was told the transmission needed to be opened for them to know exactly what repair was needed (at an expected cost of 800 $C). I visited another dealer who quickly said that all I needed was to replace the pressure control valve solenoid that is located on the side of the tranny. This is a 5 hour job that should solve the problem (expected cost of 800 $C). My usual mechanic also scanned the car, found the torque converter code. He concluded my transmission needed to be rebuilt at a cost of 1,700 $C. I also consulted with local tranny repair shops. You will not be surprised that they concluded to a full rebuilt. I am prepared to have the car repaired but I don't feel like rebuilding the tranny, if I don't have to, as I don't expect to keep the car for another 10 years. Could someone tell me if the Torque Converter Solenoid can be replaced without opening and dismantling the transmission or not ? I don't feel like spending 800 $C to replace a switch and then have to rebuild it a few months down the road. I have read the forum that goes back to 2005. Thanks to the contributors.

From everything I have rad on this forum and on another, you do not have to open up the transmission to replace the solenoid.
 
I would go with the dealer who suggested replacing the pressure control valve solenoid. This is a common problem with the Intrigue.

Thank you for following up. I intended to go back to that dealer making sure that we are on the same page as this also being the solution to the Torque converter clutch circuit.

I went back to the GM dealer earlier this week and was able to have a scan performed while the harsh shifting problem had showed up on the transmission. On top of the above code, they found code p0748 which seems to be another solenoid. He pulled out a bulletin and concluded that changing solenoid switches located on the side of the transmission would solve the problem. Is this only one solenoid causing all those codes ? From message #22, I read that the TCC solenoid was located in the valve body ( located inside the tranny ?).
