Different part numbers AND different suffix letters. My guess is there is a difference. Even with the same part number and different suffix letters there is a difference........ Much like the oil pan dipsticks.

I would not attempt to install a transmission oil pan / filter assembly with a part number different from the original. Or even one with a different letter suffix.

I've noticed this too. I'm not certain, but I've seen this "new" part number listed for the GC too. With the cheaper price point, they probably shifted production from Germany to China.

[EDIT] Okay, did some poking around... the 68142478AB appears to only be for the 8HP45 according the Mopar site.

Has anyone looked at the physical side of removing the pan/filter from their Jeep?

I looked at this in October and found that the front edge near the engine interface is blocked by a cross member. I wasn't able to get a 1/4" drive with socket in there to remove the bolts. I tried a gear wrench with a torx bit but the cross member is in the way.

oh ok sounds good, so part number we need for the GCs is 68225344AA, so we are stuck with the expensive one. so $227 for that and $17.46 a bottle for the fluid if you buy the case.

I just crawled under and looked myself. Yeah, it looks pretty tight. I wasn't able to take the sound deadening material off to get a good look. Guess I'll find out next weekend.

That's what it looks like. Everything I pulled up on Mopar's part search only mentioned the 8HP45 with this filter. I could be wrong... only taking a semi educated guess here.

Anyone have the torque specification for the transmission pan/filter bolts?

Trans oil change?

Okay, fluid and filter changed. Front 4 bolts are a PITA thanks to the crossmember just below them. I torched and bent a T45 L-key wrench to about 22 degrees. 45 degrees would have been too much and hit the crossmember.

Glad I did change it. Magnets were covered in in metallic sludge (see pics). Fluid was very dark too.

It's amazing how much smoother everything is shifting now. I just thought the last TSB made things worse.

Thanks for everyone's input. It wasn't too bad of a job. Took roughly 3 hours... with most of that for drain time. BTW... This was at 25k miles.

Re: Trans oil change?

How did you approach it, did you drain and measure exactly how much came out?

Also refilling how much could you pump back in before starting it to add the balance.

Watching the video of the Diesel Ram, the guy could of measured how much came out, claimed about 5 qts and it looked when he initially filled it, he poured 1 qt of Lucas into the pan and pumped another 2 qts of Amsoil Signature for total of 3 qts before it started coming out of the filler hole. He indicated he would top off doing the Factory procedure. I would use the Lifeguard 8 for warranty.

I would rather just do 1 for 1 knowing how much drained and then double check using the factory procedure but unclear when refilling wether one can simply pump the full amount into the trans with the engine off or wether your forced to puch some of the fluid forward into the rest of the trans with the engine running to finish the top off.

Can you provide details?

Thanks for the pics!

OH can one reinstall the drain plug into the pan if they want to do drain and fills and change some fluid without changing the pan?

Re: Trans oil change?

If was approximately 5 quarts that came out. I followed the same procedures that ramecodiesel showed in his video. I got roughly 3 quarts in with the engine off before it started to weep out of the fill hole. Then I started the engine, placed it in drive for 5 seconds, then reverse for 5 seconds and park. Then I pumped the remaining fluid in with the engine running. Fluid just started to weep out again as I finished pumping in the last of the fluid. When I do it next time, I'll be sure to have 6 quarts on hand just to be safe. 5 quarts just got me there with nothing left.

Re: Trans oil change?

"OH can one reinstall the drain plug into the pan if they want to do drain and fills and change some fluid without changing the pan?"

I played around with my old pan and plug to check this myself. It is possible, but I would suggest having a spare on hand if you try this. The entire pan and drain plug is plastic. As I tightened the old drain plug back into the old pan by hand, the slot for the Allen key broke. This would make removing it to drain again very difficult. It was secure and probably wouldn't have leaked, but you just never know. If you attempt this, my advice would be to follow the torque requirements very strictly to ensure you don't break the plug. I do not believe it was designed to be reused and felt a little brittle, probably from the heat cycles. However, that is pure speculation on my part.

I changed the filter and fluid today on my transmission at 47K miles.
I bought a Wiha T40 L-wrench bent it like suggested earlier in this thread. The job was about 3 hours with the biggest pita being the front 4 bolts. I recommend treating the new bolt with anti-seize. I saw corrosion on most of them that could prevent easy removal in the future or cause thread damage in the case. I have the factory fiber shield installed.
