Little update:

Drove the car home last night after the tranny was pretty well warmed up, seemed to hold a pretty steady 140-150 on the way home. Jumped on it pretty hard every turn i made and even stopped on some back country roads and jumped on it, got the tranny up to about 160 degrees and didnt have any shifting problems at all. Once my tranny got to around 160 (with stopping and jumping on it) my scangauge stopped displaying trans temp and it hasnt displayed all day today...any suggestions? All other parameters work just fine, just doesnts how anything for trans temp...? I continued rest of the way home, with normal driving and doing a few more pulls and the thing shifted flawlessly the whole time...figures..haha

I also noticed that my car has a slower shift time when accelerating hard (around 2200 ms) compared to around 555-700 ms when accelerating casually...is this common? I have also heard that a slow shift will throw the P1811 code....must be a slower shift than 2200 ms because its still not showing any codes :(

Thanks for continuing to help!!! Its greatly appreciated!

Hey Guys,

Yet another update:

Today we had our worst winter day of the year, around 18 degrees, gusting winds around 40 MPH, and heavy lake effect snow accumulating around 8 inches and counting. I was at my parents house when this started and was driving back to to school about 45 miles away.

I get heading out, and while running around 45-50, i notice my car not shifting into overdrive, when usually it shifts in around 40 MPH. I come into a small town and catch a light, go to take off and my car gives me a hard shift (shift time of 50 ms). I had a couple stops until I got back to country roads, and EACH time, the car would have a hard shift during the 1-2 shift, and also the 3-4 shift, the 2-3 shift was FINE...

Checked DTC'* and i see this:

I was shocked but happy to see this as my car is 600 miles out of warranty. I was surprised, because my car has only acted up like this before when transmission was completely warmed up, not 20 minutes into my trip and the coldest day of the year....

As I mentioned before, when I was driving my car home a couple weeks ago, driving it hard and trying to get the car to act up. During this process, my scan-gauge stopped displaying the transmission temp.

After checking my DTC'* and displaying code today while acting up....this is now what my transmission temp reads.....

I know this is some type of glitch, but any ideas of how to get it to read accurately again? Could I unplug it from the OBD-II, wait a couple seconds, and plug it back in?

I'm really going to limit my driving and take the car to the dealership on Wednesday after my finals this week and have it checked out and HOPEFULLY get the PCS replaced!

Thanks for keeping in contact with the thread!

Had a bit of a break between finals today and took my car to the dealer. They plugged it in and said "Sure enough, PCS needs to be replaced." They also mentioned replacing some valve-train while in there...? Not sure what that meant but they are ordering parts today, and the car goes back in Friday morning to get repaired! The price of the gauges has paid off already! The look on the mechanics face was priceless when he noticed I was 558 miles from being out of warranty!

I kinda chuckled and said "you know why I have been bothering you for so long?" haha

Tell them it didn't/wouldn't shift into 4th. They sould assume that to be a 4th hub shaft.

I will run it past them. When its warranty work, they cant really replace something without something obviously being wrong. Now if they get in there and notice that shaft looks warn, i would hope they would go ahead and fix that as well...

Thanks for the heads up Bill, i will let them know!

I would point out the temp reading as well. They should change the temp probe. If that'* reading wrong the transmission can do all kinds of strange things. such as not shift in to 4th. It will only do this if the fluid temp is 75* or higher.

Hey Danthurs,

Is that temp probe something that is located externally on the transmission? i was talking to the mechanic, and for them to replace the PCS, there going to remove all trans and motor mounts (which im going to have them look at the from engine mount....boots starting to crack) and slightly lift the engine, this will allow enough room to get the clip off the PCS and replace it....

Really appreciate all the input guys! Love this forum!

The temp probe is inside the trans side cover, just like the PCS. It'* near the bottom on the same wire harness.

PCS is the bigger of the soleniods on the left and the trans temp is the only thing at the bottom.

Thanks for the input guys! I will mention it and hope it gets resolved.

My list for them to Replace/Look at is:

1. PCS - certainly being replaced
2. Motor Mounts/Trans Mounts...gotta take them out anyway
3. 4th Hub Shaft
4. Temp Prone

If i could get all those cover, i would be pretty stoked...we'll see how much the dealer will do since its warranty work...

Thanks again guys!
