| I have a 99 intrigue with the 3.5L engine and I have a problem between 35-45 mph where it shifts really hard( you can feel it it almost feels like it misses 3rd. If you floor it, it will shift again at 60 mph really hard! Then I have a problem with a very high idol sometimes it idols as high has 3,000 RPM. Any ideas or any one have the same problem?? | |

Replying to: carsrfun2 (May 01, 2007 7:04 pm) The problem I was having with the hard shifting is fixed. I had new plugs and wires put in and the car is running great with more power than ever. if the dang thing would crank and not go dead while driving I may get another 100K miles. The crazy thing is...it's so random. It may crank on the first try for 3-4 days then not crank.

Replying to: mtram (Mar 05, 2007 5:55 pm) My 3.5 is still shifting hard, transmission I checked my trans fluid and it has the metal color on my rag. Anyone have any ideas?

Replying to: pastort (Dec 29, 2005 7:17 pm) GM 4T65E - 4 speed automatic transmissions found in many 1997 and newer vehicles equipped with the 3800 engine and most 2000 and newer vehicles with the 3400 and 3500 engines. Description: Everything is fine when you just started engine. (It’s just fine when cold) Sometimes after a long drive, stop and go traffic, or when accelerate really fast. All of the sudden you’ll notice "hard shifts" where car slightly jerks when it shifts. Shutting off the car for few (10 minutes) will make this condition go away until you drive a few more miles or the vehicle warms up and the hard shifting will return. (Notice Check Engine light remains OFF) This is perhaps one of the most common problems with this transmission. It has been a problem since the release in 1997 and can happen for no reason at all even with clean fluid and very low mileage. Solution: Replacing Pressure Control Solenoid or EPC will most likely correct this condition and again is probably the most common problem found in any year of this transmission. Details: The EPC solenoid controls line pressure and has a spool valve which oscillates back and forth to regulate transmission line pressure based on commanded pcm signals dependant on lots of various inputs from the vehicle. The spool valve in the solenoid will bind up and cause loss of pressure control from the pcm. The pcm constantly monitors shift timing in milliseconds and if this is not within programmed parameters after a few shift cycles the pcm triggers trouble code P1811 which is Max Adapt/Long Shift. This code will not set the Engine Light but will dissable all adaptive shifts and will max out line pressure in the transmission which causes the harsh shifts... Other solution is using premium engine oil to keep systems running cooler. I have 2000 Oldsmobile Intrigue with 155.000 Km. when it started happening. Valvoline engine oil worked-out as an alternative solution to replacing EPC the Electronic Pressure Control Solenoid |

Replying to: gur1 (Oct 17, 2007 8:04 am)  2k and I have had the transmission fluid and filter changed every 30k. My transmission is the 4T70E which has never returned a code.  On a side note: If you're thinking of ever changing from Dex-Cool to green, I advise against it. What will happen is the green will eventually start to pit the metals inside the engine. My engine has always had the Dex-Cool and it's never caused any of the problems other people report. This could be due to the fact that I have always performed every maintenance task in at least half the recommended scheduled time. I completely understand that not every Intrigue has the same reliability, however if maintenance schedules were performed in half the time (or at least earlier) than the manual suggests, perhaps many owners issues may be avoided. Just some food for thought.

Replying to: intrigued2own (Nov 26, 2007 5:36 am) The issue is not Dex Cool but the poorly designed upper intake manifold gasket in the 3.8L engine. Very common issue on all GM small block V6. finally came out with a re-designed gasket in 2003. Many of the issues folks are having with the Intrigue has nothing to do with the maintenance schedule. Blinking headlights caused by a poorly designed alternator; poorly designed intermediate steering shaft; upper intake manifold failure (3.8L); problems with crankshaft position sensor; faulty ignition switch; excessive oil consumption; Secondary air pump; and it goes on and on. Maybe there are poorly designed parts in the vehicle instead of lack of maintenance that has caused many of the problems. Just some food for thought.

hello my father has a 2000 olds intrigue with over 200,000 miles on it. the transmission does not have a whine or make any other noises, shifts smoothly, not hard or jerky, but does not shift into overdrive any longer. this just started last week, which was about a week after (with help from others on this forum) cleaning the throttle body, maf senser, air filter and replacing the crank position sensor. don't think they should be related but mention just in case. has anyone had this problem? or know of a fix for it? i know the car has lots of miles and owes him nothing but he wants to keep it for a daily driver and keep miles off of his 95 vette and moms 04 caddy deville. thanks for any help you can provide for this problem. the info on this sight was very helpful in repairing the above mentioned problem with the crank sensor. jman
