Jeep/Dodge/Chrysler/ZF 845RE/8HP45 Transmission Service

[@danjoe22]

Great job on what I consider to be an overly complicated set up and service procedure. You are very methodical in your approach and have a lot of cool tools. I have a 2015 Chrysler 300C with the hemi engine, currently 34000 miles. Given the condition of the fluid you replaced I feel confident that my car could go that long without need for service. Thanks for being so thorough and providing good advice and commentary.

[@NanoDiaz777]

Hi Joe, out of all the videos I've seen, this is the best because you make it simple and it works. I just have one question, in the final part of the procedure, did you go for a ride in the Jeep? Or did you shift gears with the brakes pressed while in the parking lot? And how should I make sure the jeep is in a good position to be able to put all the necessary oil into the transmission? thank you!!!!

Great video. I changed the fluid and filter on my 2015 Grand Cherokee last week. Ordered the Mopar filter and all was going well until one of the pan bolts broke (in the corner - under the cross member). Tried to remove the bold using a bit of heat (propane torch) but was concerned about using an open flame. Put it back together with the old bolts (minus one) and so far-so good on the leaks. I'll check the fluid level when I change oil next month. Thanks for all your help with the videos.

There's one sitting in my driveway so I should be able to accommodate that request :) It looks WAAAY easier on the RAM though. The last time I was under there, the front and rear pan rails didn't seem to be blocked like they did on the Jeep.

[@Grumps5]

Just did this job today, It was a royal PITA since I did not have any hex wrenches available. Propped up the T-Case a few inches to gain more access. I went with Redline D6 for the fluid (it's red but the vehicle is out of warranty already) & supposed to be a superior fluid to the ZF/Mopar stuff as well as cheaper. D6 is popular in the Trackhawk/SRT8 scene. Great video! The pan I used to replace it does not have a drain plug for some reason? It's a Mopar part direct from the dealer so I guess that's a new thing. Perhaps trying to curb people from working on their vehicles even more I bet. I went ahead and installed new hardware as well + a new drain plug.

[@JoesGarageProductionsLLC]

Thanks for the complement! Let me know how the Redline D6 fluid works out for you. Odd they would remove the drain plug, but I guess every penny counts.

[@supermariobronsmiranda6735]

Hey Joe great video but..........Im a bit skeptical abut the level check at tranny temperature procedure. Don't you have to set the tranny on drive, rev up to certain rpms and hold it at second gear for about 5 seconds? That being said don't you have to raise the rear tires to do this?

[@JoesGarageProductionsLLC]

Thank you! Honestly I'm a bit skeptical of the true importance of that fluid check procedure in the service manual. I spoke to a transmission expert that confirmed my suspicion that as long as you get the fluid level reasonably close you'll be fine you just want to avoid drawing air up into the pump and you also want to avoid fluid aeration caused by contact with moving parts. That said the vehicle has been a daily driver since this video was shot and we've had zero problems

How much fluid can you expect to drain out? The entire system takes 9 qtrs. but if your just doing the pan I would expect you will only get about 4 maybe 5 qtrs.

Correct. I believe mine took about 5 quarts. I think I mentioned the exact quantity at the end of the video

Great video. Would it be the exact same procedure if it's a 4x4? Would it be harder? I want to do it myself to save money but also because it's hard to find a shop you can trust and do it right or even do it at all and still take my money. Problem is I. Afraid to do it , fearing I'd do it wrong.

[@JoesGarageProductionsLLC]

That's probably going to be more difficult on a 4x4. You going to have the front axle and drive shaft to deal with so things are going to be even tighter than a two-wheel drive vehicle. It can be done though. There are a couple videos on KZbin showing the procedure for a 4x4

[@swimers100]

How much you think it will cost if I take it to a lube place or transmission service place to do all that procedure? Would you trust them to do a good job like this ? Thanks

[@JoesGarageProductionsLLC]

I would not trust a run-of-the-mill lube shop to do this kind of work. This transmission requires a fairly specialized fluid that I doubt most shops would keep in stock. That's a very generalized statement though. I'm sure there are exceptions to that rule. Judging by the cost of just the materials, this will likely be over $1,000 at a dealer but I can't say for sure as I have never paid a dealer to do this.

[@kjhnsn7296]

You are correct. $1200 - $1400 are the numbers I've gotten.

[@Electricmarquis]

Did this today on my 2014 Durango 3.6 awd. Only got about 4 qt back in. Should have measured what I took out but did not. Its hot here so, will have to let it cool overnight and re-check in morning. Durango is very much same as the Jeep. Most seem to bet getting 4.5-5qt in. Any thoughts? Did you level the car or level the trans?

[@JF32304]

He leveled the car, I have a GC and I pulled out 5.5 and am at 4.2 right now. I'm going to let it cool overnight and run the process and procedure tomorrow and see.

[@lrncephil80]

ZF says you can use Valvoline max life atf

[@JoesGarageProductionsLLC]

Really? Is that new? Regardless, I believe Maxlife is red in color. God forbid if I ever needed to make a transmission warranty claim, I am sure they would deny it if they saw red fluid - or, at the very least, I'd have more work to do to convince them it is an approved fluid. Technically, while ZF designed this transmission and licensed the design to Chrysler, the transmission was modified by Chrysler and Chrysler makes the 845RE. The 8HP80, on the other hand, I believe is purchased from ZF as-is. At least, it was as of a few years ago.

[@oboyglooms]

Does it have a gasket that needs to be replaced?

[@JoesGarageProductionsLLC]

Yes the oil pan kit comes with a new seal and new bolts

[@ak540i2]

Is this Mopar fluid the same as the ZF Lifegard 8?

[@JoesGarageProductionsLLC]

I have heard that they are interchangeable, but don't know for sure. I suspect that Mopar buys the fluid from ZF, who probably paid an oil company to make a custom formulation. Everyone in that supply chain is probably taking a cut!

[@TheNipSnipper]

I find it really irritating that it's so difficult to find out which specific transmission is in my jeep. The owners manual doesnt say anything about the trans other than it takes Mopar atf+4 or equivalent. And the Haynes manual I have says all the transmissions that are in all jeeps in a given set of years models... But doesn't say which trans goes in which years or submodels... Idk if anyone knows but I'm still looking. I drive a 2013 grand cherokee 5.7L laredo 4wd. if you know pls share.. I don't know much about transmissions.

[@JoesGarageProductionsLLC]

I don't think it's a bad idea. It all depends on whether or not you trust Chrysler or the company that designed that transmission originally. The design is based off of the ZF 8HP, and if I recall correctly ZF wants you to change the fluid at approximately 60,000 miles. Chrysler says it's still for life under normal conditions
