Transmission Fluid Replacement at 50k.

I am planning on replacing my trans fluid every 50k, yes I know its supposed to be fill for life, not. I do tow and drive it hard.

Has anyone replaced their Trans fluid with anything else other than Lifeguard 8.

Have been looking around and the Fuchs 4132 seems to look okay and seems to have been used buy the Landrover guys with great results as they also have been using the 8HP70.

Also thinking of putting in a remote filter so that filter thats built into the pan doesnt have to be replaced.

There is also Motul and Redline but cannot find multiple accounts of people using it.

Also thinking on getting a oil analysis done.

Cheers

Re: Transmission Fluid Replacement at 50k.

Yeah, 50k kms is pretty early, I think the recommendation in Oz is 100k if towing. I had found a good youtube clip on a US guy changing his ram1500 trans oil and filter and he suggested something different for fluid, I'll see if I can dig it up.

Found it:

Thanks Benno saw that already.

On all my previous cars I have always changed the oil myself at 50k and ran a remote filter.

Is 50k a bit early, probably, but planning on getting both a engine oil and trans analysis done and we will see what the go is.

Just to clarify, you're planning to change at 50,000 km (aka 31,000 miles)?

Re: Transmission Fluid Replacement at 50k.

The ZF transmissions are very, very fussy when it comes to oil. Personally, I'd stick to Lifeguard 8, but then personally I would wait till 100km, specially if you are not towing. You really are just wasting your money. The ZF's are a generation better than the old transmissions.

I'm with you chocco. I also plan to do mine at 50,000 Klm's. Would rather over service my vehicles, knowing that prevention is better than cure, rather than under service and be wondering.
Can never understand why people would spend big money to buy a new vehicle then stretch out the servicing intervals to the absolute maximum.
I know that I would be more than comfortable buying one of your vehicles chocco, as it sounds like you look after them

Re: Transmission Fluid Replacement at 50k.

how do you guys that DIY drain the convertor? is there some procedure that can be done without equipment? or is this just pan drop and fill to level?

Re: Transmission Fluid Replacement at 50k.

I have a great deal of experience with ZF trans and one thing is for sure. Use other than LG8 and you are experimenting. ZF transmissions don't do well using other fluids.
I know for ZF 6 spd trans that Mercon SP is approved but do not know about any other.
I drain and refill at
50K miles and have done oil analysis at Blackstone with 6 spd trans same mileage. Report back is that trans had a lot of life left. However doing drain and refill only gets 50% out or less so every 50K drain and refill has taken me to over 200K miles on other ZF trans.
Be aware that the drain and refill procedure is very specific and is not just drain and refill but drain and refill to weeping then plug the fill port start the engine and run the engine while
Opening the fill port again waiting for the trans fluid temp to get to between 80F and 120F until weeping again. Again with the engine running.
I get my ZF fluids from CTSC in Ca by the way...

Re: Transmission Fluid Replacement at 50k.

shoot these guys a message, bndautomotive.com . Their lubes are suppose to be good stuff especially the trans fluid. They also sell the fluid and new pan as a set. They also claim to make you a custom blend fluid to your specs if you like.

Here is a reply i received and inquiring about their trans fluid

Quote:
Santana,

Yes, we make the QuantumBlue 8HP70D transmission fluid and provide the filtran assembly with gasket.

What you have is the 3.0L V6 which has a part number of 68225344AA and has a retail price of $335.00.

We can provide the pan for $260.00 and the fluid for $28.55 per quart. Both of these are specific to the 8HP70D transmission.

Our fluid is better than the $43.95 Lifeguard Fluid the OEM sells and the pan is a direct fit with all the bolts and gasket included.

Here is one we just did for a customer with a 1500 Ram 3.0L with the 8HP70D
(there were pictures of the pan and the fluid)
There are aftermarket companies that are trying to say they make the fluids for around 12.95 or 13.95 but let me assure you that these fluids are trying to work with the lower HP and torque versions 8hp45 or 845RE.

These fluids will not hold up in the diesel application and burn up quickly. There are special modifiers necessary to make the diesel function properly.

Simply give me a call and we can get it going for you! Looking forward to working with you!

Re: Transmission Fluid Replacement at 50k.

I would stay with the lifeguard fluid everyone I have talked to says don't deviate from the lifeguard fluid as these trans are particular. if you buy a case of 12 the genuine lifeguard 8 fluid is $17.40 each at the link below. I would not risk putting some other fluid in it.

ZF LifeGuard 8 - Case of 12 x 1L Container

you can get a mopar pan filter for $248 on ebay there are other online dealers less than that also

Chrysler Automatic Transmission Filter 68225344AA | eBay

id like to see that pan filter price come down but it is what it is now maybe in time it will. Fluid price at 17.40 is good compared to what mopar wants for it.

Thanks everyone for your input, replacing the fluid and filter at 50k is not for everyone and I am basing this on my driving style and towing, heat is the biggest killer of the trans oil and Jeep got it right with this setup, so chances are everything will be fine, but if its not then all the better.

When I drop the fluid and get a Blackstone test from those results I will then determine if I push it out further or just drop oil only at 100K or oil and filter.

The main reason for posting this hot potato was to get people talking and find out about alternatives to Lifeguard 8 as there is not alot of info out there.

I had a Cross 8 before this and when AUS stopped using the 4L65 trans the US still used them but then changed from Dex 3 to Dex 6 but in AUS the spec was still for Dex 3. I swapped from Dex 3 to Dex 6 and the difference was night and day, people thought I was nuts.

So the more people who comment on this Lifeguard 8 topic of alternative oils a better choice can be made on which one to use.

Keep it coming.

Cheers
