I do not see any bolt to add or remove the transfer case fluid. The transfer case seal is also leaking near the transmission.

Hi Dilli,

Here is an exploded view of the PTU. If you provide the VIN (last 8) I can get a part number list as well.

Let me know if you need anything else. Thanks

The Vin Number is 1B3LC46J38N177606. I think it has 41tes A604 Transmission. The transfer case fluid change is needed.

Based on that VIN it shows you have a 40TES. Commonly interchangeable terminology with 41TES.

However, I don't show a transfer case on this vehicle. It would be called a power transfer unit (PTU) but it doesn't show available on this VIN. The PTU in 2008 was only available on the 62TE transmissions which were available in the R/T model with the 3.5L.

Can you take a picture of what you are referring too? Is it possible that you are looking at the differential next to the transmission? Do you have a drive shaft going to the rear axle?

I have shown what’s leaking. It’s connected to the transmission.

Excellent!

That is the differential. You remove that cover that should have 12 bolts around it. Then you reseal it with silicone. I attached the procedure as well to just drain and fill it but you need to remove that black cover and reseal it.

I have changed the Valve body and shift control block and all the sensor. Now the car moves in 1st gear but It does not shift into 2nd gear. After first gear when It try to shift into second it feels like in neutral. I am getting 3 code P1607 P0700 and P0732. I think its maybe because of bad PCM. I have eliminated all other option. Do you think a bad computer will not cause to shift into 2nd gear. I have changed the input and output speed sensor
Is code P1607 Realted to P0700 and P0732
Please Help

The P1607 is not related to your two transmission codes. I included the tests and descriptions for each code. Basically, the P1607 is a failure in the internal temperature counter of the PCM. This could be caused by an Engine coolant temperature sensor or circuit but it is looking at how long it takes for the engine to cool down. It expects to see the coolant down to a certain temperature after it is shut off. If it does not see this then it sets this code. Usually, when you have just this code and no other coolant temperature codes then it is the PCM. I would run through the test just to make sure but I would address this code first because if you have to replace the PCM it may fix your other codes as well.

One thing about the P0732 is that this is what is preventing your shift to second because it is not seeing the correct RPM ratio between the input and output sensors. Again, I would address the other two first but this one may remain after you fix the others.

Let me know if you need more information. Thanks

P1607 Code came because I disconnected the battery when engine was warm after clearing it that did not come back. The other two codes P0700 and P0732 I diagnose as much as possibly I cloud and the same problem is happening again. The car does not shift into second gear. I even replaced the speed sensor. I think it could be the computer problem or Internal Transmission. I think It could be the bad TCM. What do you think about TCM? How can I find out if the second gear is out. I have OBD2 cable and computer which gives me live data. I will replace the computer and if It does not work then last option I have is to replaced the transmission from Pick a Park or Junkyard that has same transmission.

Okay. If those are your only two DTCs then you need to fix the P0732 first. Ignore the other for now. If you look at the attachments that I gave you last time, the P0700 tells you to address other transmission DTCs first.

The P0732 is telling you that when it is trying to shift into second gear that the gear ratio is not correct. That means when the TCM commands second gear, it expects to see a specific speed of the output shaft speed sensor.

This means you have an issue with the input or output speed sensor on the transmission. An issue inside the transmission with the solenoid pack not apply the correct gear. Or the clutch packs inside each gear set are not able to be applied.

If you have a scan tool then you need to follow the diagram through. It appears this will lead you to an internal transmission issue not a computer problem. However, look at the diagram for the P0732 that I attached and just read and answer the questions that it asks and it will lead you to the fix.

Hello sir, I changed the whole transmission. I replaced the transmission from Pick a Part. I had 80,000 miles on it and it is pretty good condition. I added new fluid and filter in the transmission. I also changed the old the electric connection to the transmission. When I start the transmission for the time it shifted into the drive, reverse and other gears fine. Then I drove about three miles and it was shifting very smoothly then it started acting weird. The first thing I noticed it started delaying the transmission gear. For example fourth gear is supposed to shift at 45 mph but it wont shift until 55 mph. Then I stopped in parking lot checked the fluid and it was at good level. Then I started the car again and I noticed it engage into drive late. When I shift from park to any gear it takes about two to three seconds to engage. And then it started jerking when shifting. Everything was fine first three miles. But then It was acting weird. I even cleared the any codes before the starting the car for first time. The code that I am getting is trouble code P700 MIL Request and Freeze frame Data P0732. These codes were coming from the old transmission. I cleared it but then came back on. It shift in and out of second gear but not very smoothly. I am assuming that it is the computer gone bad. Please help me so I can fix this car. Please help me sir

Sorry to hear you are still having these issues. This leads me to think there is another issue on something that effects the shifting of the transmission. This could be the module but not necessarily.

The P0700 is telling you that you have another code in the TCM which you do, P0732. However, if you read through the testing it tells you to test the wiring between the PCM and TCM.

The P0732 tells you that the TCM did not see the expected speed on the output speed sensor on the transmission. However, you said earlier that you changed those already.

I would follow the p0700 and test your wiring before replacing the PCM. However, based on everything you have done, it looks like all that is left is a PCM. PLEASE run through these tests again and don't assume the parts you replaced are good parts just because you replaced them. I would hate to see you replace the PCM and then it doesn't fix it because you got a bad speed sensor or your replacement transmission also had a second gear issue. I have seen this happen.

If everything checks out, then a PCM would be my next part replaced.
