2000 Intrepid tranny replacement....

It's time to replace the tranny. Last year I swapped out the crappy 2.7L for the beefier, more reliable 3.2L motor, but kept the 2.7 tranny & ECU in - which some forum members suggested would work and others objected to. I went for the cheaper route.

Not a shocker that the computer read several codes, including Gear 1 & Gear 3 incorrect ratio.

So according to the dealership parts department, a '99 or '00 of the following cars will also have the same transmission as my 2000 Intrepid: Chrsyler Concorde, Chrysler New Yorker, Chrysler 300M, Chrysler LHS and the Eagle Vision.

I imagine the aforementioned makes & models also have the same ECU and TCM (transmission control module) as my 2000 Intrepid.

If any of that sounds incorrect, by all means let me know before I waste cash on parts I can't return.

Thanks in advance.

99 thru 04 transmission will work. From any LH vehicle. Make sure its a 2.7 vehicle though so you keep the 2.7 gears. No need to change the TCM or ECU. Just plug and play. Eagle Vision uses the older style transmission, the A606, so they are not compatible (nor would you want one in your car, lol).

Before you replace the transmission, did you ever troubleshoot it to see what the cause of the codes were? Could be something as simple as the input/output speed sensors, which is a common failure.

The Input Speed Sensor Circuit was one of the codes that popped up and I intend to replace it.

But, I don't think that would cause the tranny to jerk violently when I shift to Reverse or Drive, or cause it to stick instead of shift when I'm driving.

I plan to pick up a tranny & torque converter from the Pull A Part yard, which adds up to a dirt-cheap price of $89.00 with tax. Most junk yards around here would charge at least ten times that much.

I suspect it might just be the torque converter and speed sensor that need replacing (for now) since I only have 121K miles and my transmission functioned just fine for a whole year after the 3.2L was put in.

Cant beat $89 dollar price for a tranny. Heck the speed sensors are $40, lol.

Bad input sensor does cause a limp mode condition (not shifting, stays in 2nd). It could cause the banging into gear as well.

Really??!! All of that from a sensor??

According to the dealership, it's the sensor closest to the engine, on the drivers side of the transmission. It should be pretty simple to replace so I'll start with that.

And I'll be more than happy to sell you one for $30 since they run for about $24 brand new around here. ; ) But if Pull A Part sells me a used one for a few dollars and that's all it takes to fix the problem, then this might just be a good weekend afterall.

Yeah, these trannies are shifted electronically, so if the TCM doesnt know the input speed, it gets quite "confused", lol.

Replace the output sensor as well, (can cause issues like this as well) its about 6 inches to the rear of the input sensor, which is about half way up the drivers side of the transmission, a few inches back from where the cooler lines attach.

IIRC it was $40 for both sensors at the dealership. Could be a little more. So I'll sell you both for $45, lol....

Thanks again for the help. I'll be back in the next day or so if it turns out the sensor was just the tip of the iceberg. Hopefully that solves it though.

You were right so feel free to post a How-To about ass-kissing so I can follow it.

To no surprise, my front passenger tire decided to pick up a screw and go flat 24 hours after the input & output speed sensors were both replaced.

Oh well. The big probs are over for now. Thanks again.

Sweet! Your welcome. A little bit easier than changing the whole trans eh? Glad that was it. I'll have the how-to up soon :biggrinfl

Sucks about the tire though.
