Hi guy's .

Since 2 month, i have a good Oldsmobile Intrigue 2001 GLs with the Precision control Package. The hot time is back ans my transmission have hard shifting, in intermittence.

I'm going to change my trans fluid with a new filter but i'm sure it will not help, so i'm looking for a new transmission. But the hard part, is to find a transmission it will fit with my precision controle package with the 3.29 gear ratio.

What can i do ? I've read a can take a V6 Oldsmobile Aurora Trans ?

Thanks in advance !
 
As far as I know the 4T65-E was the only transmission available in the Intrigue. You could get different gear ratio's in the form of an Autobahn Package, GLS trim, but that's it, just different gear ratio's. I'm fairly positive the Precision Sport package gave everything the Autobahn did except upgraded 12" rotors. If you buy a transmission through a rebuild company, they are going to ask for your full VIN that will tell them everything they need to know. Precision Sport package made no changes to the transmission other than gear ratio, so don't let that title throw you off.

Just a quick note, if you are sure your transmission is getting ready to fail, I would save some $$, and leave the fluid alone. I've talked to transmission guys who have told me the old fluid contains metalic particals from the clutch plates and these particles help keep the transmission clutch plates grabing, fresh fluid causes major slippage.

But the PCM will be ok with a different gear ratio ?

So if i take a transmission from a GLS 01 Intrigue without the Precision control system, it will be ok ?
 
You're making me glad I got a vanilla GL with the 3.05 gear. Should be a sinch to match if I need a rebuild.

For what it's worth, the 3.29 gear was in GLS model years 1999 to 2002. And I think GL Intrigues in 1999 had the 3.29 as a quirk of the cutover to the new engine. Getting the gear ratio match, shouldn't be a hard search. But whether it matters if the previous car had PCS is a different question...

I have read a few articles of guys rebuilding the 4t65-e, making it an hd model, and changing gear ratio's. Never recall any mention of computer module compatability issues. When I worked @ AZ, I looked at the rebuilt transmissions we sold, and every company said full VIN required for ratio match, but on other w-body forums, guys are asking for gl vins for the 3.05 ratio, and others are asking for 3.29 vins. Leads me to believe electronics aren't an issue.

In regards to fresh fluid ruining the trans, I really think this would only be the case if it was on its last legs anyway. I've had rough and erratic shifting that was solved by a pan drop with fluid and filter replacement. That would always be my first course of action before looking to replace the whole thing! I only do the pan drop method of changing the fluid though, I don't trust the flushing machines on a high mileage trans.
 
what you describe is a pressure control solenoid sticking issue and might be cured or eliminated by a seafoam transmission flush, followed by a switch out and change to synthetic fluid.worked for me.good luck.
 
@christuaph- your right, I should have specified flushing the tranny will send it out the door if it's on its last leg. A pan drop, and filter change only replaces approx 70-80% leaving the old fluid in the torque converter. Now that it's been mentioned I'm reminded that I need to go ahead and drop my pan and change the filter. There's a new fluid GM developed that looked good in the article I read so I'm gonna have to add it to the to-do list.
 
I would not use a different transmission on a vehicle with PCS. PCS is ESC - electronic stability control, that applies brakes to keep the vehicle from skidding under some circumstances. I think you might encounter some compatability issues since the control unit for the PCS will be looking for what was originally there.

I would like to think they took that into consideration with the new fluids? :confused:

@Ballenxj-I should have clarified, the old tranny fluid has clutch particals from normal usage, and when I've talked to rebuilders they say if your tranny is slipping not to have a "flush" done because these particals help. Haven't confirmed one way, or the other personally, but it makes sense.

Yeah, That makes sense if your tranny is on it's last legs. ;)

Sorry for bringing up an old thread, but in case anyone in the future is wondering if they have to replace their transmissions, the precision control system didn't do anything differently for the transmission itself.

If your Intrigue is equipped with the PCS, your transmission will have the 3.29 gear ratio. If it doesn't have PCS, the only possible way it will have the 3.29 gear ratio tranny is if it is a 99 GL or GLS (some had them).

That being said, if your tranny does need to be replaced, look on the trunk lid for the RPO code FR9 - this is proof that the car has the 3.29 gear ratio transmission.

F83 RPO code is proof that the car has the traditional 3.05 gear ratio transmission.

Computer programming is different, so you will need to make sure to get the correct one.

Useful information, THANKS. Now if I could only find those codes in the trunk of my Aurora. I looked and they were nowhere to be found. Was that an Intrigue only code? :confused:

Auroras with the 3.5L have 3.29 gears. They need it, being a little heavier.
 
Correct with both statements. The Auroras had the 3.29 gear ratio transmission for the 3.5 models. I'm not quite sure where the RPO code sticker is on the Auroras, though, because they have the carpet panel on the trunk, correct? Or some of them do.?.?.

Yes, My trunk is carpeted.

Since the winter is back, approximately 3 months, no trouble with the trans.

So, maybe i only need another oil change ? The selenoid is stuck only when it's hot outside ... very weird ...

You know you may be on to something here. My Aurora hasn't had the hard shift problem for most of the cold months either. :confused:
