Jeep Wrangler JL 2020 | Automatic Transmission 850RE | Transmission Fluid Change | Lifetime Fluid

Jeep does say there is no transmission fluid change needed, at least in the maintenance manual. Zince the manufacturer ZF of this automatic transmission required a fluid change I believe every 50k or 60k miles I just want to be proactive and do something good for my car. Since there are not a lot of this kind of videos out there I hope this is helpful for you. Below you can find the Mopar parts I used as well as the transmission fluid from Mopar is linked.

Isn't it strange that Jeep tells us it's a lifetime fluid, but ZF, the transmission manufacturer recommends service every 40-60K miles. 🤔 Thanks FCA!

[@tobisreallifeskillswithtobi]

I don''t even know what to say about this - but yes, it is strange and bothers me a little ;-) That's why I did this video and the service myself! :-)

[@richardarceneaux4514]

Did mine today at 66,000 miles. Took about 3 hours. Mopar fluid and gasket and filter.

[@mohammedalkhamees5940]

Thanks for your wonderful video it’s really helpful , I have Jeep Wrangler JL Rubicon 2018 just wanted to know the size of the transmission oil pan fill plug is it 8mm socket same as 2020 model

[@obrianmcc12]

kudo's for a great thorough and descriptive how to ... did the fill plug not have a compression washer?

[@tobisreallifeskillswithtobi]

Thank you! No it is pretty much this one: www.moparpartsfast.com/oem-parts/mopar-transmission-case-plug-6513212aa

[@obrianmcc12]

Appreciate it ... Thx @@tobisreallifeskillswithtobi

21 Gladiator, transmission shop said to complete at 100k. Great content!

[@tobisreallifeskillswithtobi]

Thanks for watching! Interesting to hear from the transmission shop! thansk for sharing!

[@andresramirez7660]

How did your 100k transmission service went I bought a used gladiator not so long ago and I almost reach 100k but wondering if is not to late to service the trany

[@tobisreallifeskillswithtobi]

I am still below 100k at around 78k at the moment. Yes, I would so do it, not too late if you do not have any issues so far you should be good to do the fluid change

[@trail_tracker]

Do you need it to be warm when you drain the fluid? I guess so just like oil change?

[@htxgladiator]

Great video! It's been a few months since you changed the transmission fluid. How's it running so far? Are the shifts still smooth?

[@tobisreallifeskillswithtobi]

Great question and glad you asked! My Jeep is still running! Still shifting smooth - no issues so far :-) I'm monitoring the transmission fluid temp when driving and it is all normal it looks like :-) Knocking on wood it stays like this!!!

[@harimpalma7837]

Thanks for the video, I have just bought a Rubicon 2.0 model 2020, do you know if the filter is the same?

[@tobisreallifeskillswithtobi]

Thanks for watching! You might be able to check this on the mopar page with your VIN/specific car type: store.mopar.com/oem-parts/mopar-transmission-oil-filter-68417054ab

[@JoseRodriguez-do8rv]

Look into TPE trans pan upgrade.😊

[@tobisreallifeskillswithtobi]

I almost did ;-)

[@dapperbarberacademy]

Nice video! Is the drain hole and fill hole the same hole?

[@tobisreallifeskillswithtobi]

Thank you! Yes it is!

[@dapperbarberacademy]

@@tobisreallifeskillswithtobi thank you so much best video so far to transmission fluid for JL

[@rivianconsult]

Just to confirm, to get the correct fluid level you first fill to overflow, cycle the transmission through R, D1 & D2 twice then leave running in P and fill to overflow a 2nd time?

[@tobisreallifeskillswithtobi]

Correct

[@jonrichards6432]

In the UK, for 9 liters of the Mopar gearbox fluid it costs a whopping £252 + VAT (£28+VAT per litre). Wondering which oil Mopar uses and if it can be sourced more reasonably ?

[@tobisreallifeskillswithtobi]

Thanks for watching! That's a steep price. I think I looked into this as well but since the car is so new I figured to go with OEM :/ I found this, which seems to fit Jeep JLs: www.northridge4x4.com/part/gear-oil/30704-red-line-d6-automatic-transmission-fluid-1qt Here is the video where they use it for their new transmission pan: kzbin.info/www/bejne/oZK9gGeQhs97pZI&ab_channel=Northridge4x4 I hope this helps!

[@justinmeshell6585]

What was the mileage when you did the change? I am at 72k and interested in doing the transmission fluid change also. Thanks!

[@tobisreallifeskillswithtobi]

It was around 50k

[@tommym4787]

I thought they take 9.5 quarts? Hmmm maybe that’s only if you do the whole transmission flush.

[@tobisreallifeskillswithtobi]

Yes, since this is not a flush it doesn't take as much.

[@WPAOutdoors]

Where did you get that instruction sheet from? (FCA Instruction sheet K6856018)

[@tobisreallifeskillswithtobi]

It was included in the gasket package I believe.

[@WPAOutdoors]

@@tobisreallifeskillswithtobi thank you!

[@odysseyusa]

Did you say hand tight on the filter nuts and then an additional half of a turn?

[@tobisreallifeskillswithtobi]

No, hand tight and loosen half turn.

[@odysseyusa]

@@tobisreallifeskillswithtobi I just had another say, from the ZF pdf manual he supposedly has, that it’s hand tight then BACK off 1/2 turn so the o ring seal that goes into the pump can self align horizontally without binding.

[@tobisreallifeskillswithtobi]

I'm sorry! I just watched it again and said loosen half turn. Thanks for double checking! You are correct.

[@Onward4x4]

Just to be clear, this was a transmission fluid change not a flush-is that correct?

[@tobisreallifeskillswithtobi]

Yes, correct

[@shanec.7105]

Got quoted $163 for dealer trans filter gasket kit, does that sound right for what you paid? Seem overly inflated. Even the fluid was quoted $36.28 per quart. Don’t buy retail at dealer. Just for curiosity, asked for trans service at dealer and got quoted $750- $800. Not even a final number, just range from service advisor. Power steering fluid was $47.85. Everything is just getting out of hand. Affordability wise.

[@flatheadfletch]

Correct. From dealer especially. Just go to auto zone and get the European power steering fluid.

[@tobisreallifeskillswithtobi]

I paid ~70 for gasket and ~60 for filter to give you a reference. That's a steep price!

[@peterc8979]

Sounds correct pricing

[@coreybunss]

How many miles was on your vehicle when you changed it?

[@tobisreallifeskillswithtobi]

~60k Miles

[@prayerwarriorgodlovesusall8117]

What tool was used to remove transmission drain/ fill plug? Thank you, Brandon😇

[@tobisreallifeskillswithtobi]

Hey Brandon, it was a Hex Key Allen, I forgot which size - I thought I added it. Sorry I did not apparently. You can see it in 16:11 of the video. That shows the fill plug. With the OEM pan there is no drain plug. Aftermarket transmission oil pan does come with a drain plug as well like the PPE Heavy-Duty Cast Aluminum Transmission Oil Pan.

[@prayerwarriorgodlovesusall8117]

@@tobisreallifeskillswithtobi Thank you for content, and reply😇 8mm hex allen bit for jeep jl automatic 8 speed transmission fill plug.

[@wyleehokie]

How long did that take?

[@tobisreallifeskillswithtobi]

Can be done in 2-4 hours depending on your level of experience ;-)
