Transmission codes P0732 & P0846

[maddss]

04 LJ with 115k, with 42RLE 4 speed auto. Located a hole in the side of the Transmission Pan and lost a good bit of fluid. Now have the following codes P0732 & P846.

This is my plan:
change all fluid: Valvoline ATF+4,
New Pan: Mopar 52852912AC or Dorman Transmission Fluid Pan - A/T 265-818

Filter: ATP B-216 Automatic Transmission Filter Kit

Fingers Crossed that the 2 code clear themselves out

Sounds like a good plan, I hear the Dorman pan is high quality.

That sounds like a good starting point!

Low fluid can create conditions to set both of these codes.

Your plan is fine. While you’re working on the transmission, disconnect the negative battery terminal so the TCM goes into learn mode when you next start your Jeep.

If you don’t know how much fluid was lost you’ll need to start by adding 4 qts back in. Then start the engine and shift between park, reverse, neutral and drive a few times, pausing in each selection for several seconds, and check the fluid again.

At this point you should make sure you are above the cold fill mark on the dipstick. If good, bring an extra qt and a funnel and go for a drive.

The basic quick learn procedure is to perform the PRND selections and then go for a drive to help the TCM perform smooth 4-3 and 3-2 downshifts.

Drive on the highway (overdrive on) at 55 mph for 2 minutes with the A/C on then take your foot off the accelerator and coast until the transmission performs the 3-2 downshift. Accelerate to 55 mph again and drive for 5 minutes then coast to a stop. Adaptive memory can take 50 warm up cycles and 500 miles to restore. The performance should improve little by little each time you drive.

If the codes return, post back.

You have to use a DRB3 to put the transmission in "learn mode." All pulling the battery does is clear the temporary registers and some codes.

Pulling the pan and replacing it along with the filter is a great idea like the OP says, adding fluid to a transmission with a hole in the pan is a stupid idea.

Are you trolling again? If course he’s going to replace the pan before adding fluid.

Removing power from the TCM clears adaptive memory and puts it into learn mode. A DRB is not necessary under these circumstances.

It does not go into learn mode, more than that it will clear the readiness monitors which isn't exactly great.

you’ll need to start by adding 4 qts back in

See this picture of the factory service manual where it says 3 quarts after a filter change

It's in bold so even people with reading problems don't miss it. Your info is top notch, all of it, I'm sure trolling.

New Problem Skid plate bolts are just spinning !

Looks like some grinding and replacing, per other threads

You could try to pry down on the skid while you turn if it's the frame bolts. If it's the skid to skid bolts there is a square nut you can reach over and hold. If the frame bolts spin and you can't get them there are plenty of threads about how to take those off, the main skid does the same thing and I think Blaine sells replacements at blackmagicbrakes.com but I'd double check the size.

I have that Dorman pan with the drain plug and it works great. Many reviews said they had leaks from the plug because of the brass washer. I ordered these Dorman nylon washers and used them and have had no problems.

Grinding 2 frame bolts and 1 other, skid plate is off. Trans pan replaced a whole lot of fluid. It all back together with no leak and no CEL
