NEW 68RFE RevMax Series 850 Leaking?

[Palladium]

After my ATS 68RFE gave out in November, I spent a few hours on this forum, and everyone seemed to recommend RevMax.

So, I invested and purchased their series 850. It's been an absolute nightmare.

I'm not here to bash a company but hoping someone can help point me in the right direction.

The first unit arrived, we installed it, followed the relearn process, and about 350 miles in, the trans was blowing ATF from the vent, completely ruining my brand new driveway.

I called them, and they informed me the front pump may be defective.

So we had to yank it out and ship it back.

While waiting for the warranty work to be done, I got my pavers redone.

The new unit arrived last month and was reinstalled two weeks ago.

I'm about 550 miles into this new unit, and I'm getting a small leak from the inspection plate cover and two more from the pan itself.

Of course, parking in the same spot that I always do ruins my brand-new driveway once again.

On the bright side, I don't notice anything wrong with driveability.

I can pretty much rule out a bad gasket as the cause of the pan leak; however, I can't understand what would cause a leak to develop where the inspection plate is located.

I figured a company as reputable as RevMax would have some air-tight QC for these units to mitigate these things from happening.

I'm about $6k in the hole between labor on two trans swaps, ATF, and driveway repairs.

I can't afford to keep pulling the transmission out every month.

Any help would be greatly appreciated!

Hello, retorque pan gasket should be approx 89 inch pounds feel the turning of the bolt; do not jerk the wrench in case the threads in the housing may be weak.

If you feel the bolt does not tighten up and feels weak when applying torque, stop and let the manufacturer know your findings.

Next, remove the inspection plate or starter to gain access to the bore scope, see if you can place the lens at TQ to the front pump, and see if droplets are setting.

It could be a leaking TQ Drain if not checked by inspection; there are just a few things to inspect before removal.

BTW, I have found large drip trays for catching oil for vehicles; most long-term classic cars have these to protect floors from oil.

Another possibility at your pet store is that the trays in the dog kennel cage are different sizes; trays under the vehicle, when stopped, have large lips; eBay also for trays search dog kennel cage.

Just info, and I hope it helps.

After rereading, I learned that Blowing oil out of the dipstick tube is an expansion of fluid due to overheating; I'm curious about more than one Factory-ATS-Now RevMax.

Did you replace the tank in the radiator for the cooler, or did the radiator assemble it and then replace the front air to the fluid cooler?

With the Unit failing, these are heat-related.

If it is now 500 miles long and could still be overheating, it will cause leaks and very thin fluid.

Doing a cooler flow test, first and foremost, helps prevent pulling units or failure and warranty denial.

Factory thermostat trans cooler blocks have failed and cooked many transmissions.

When dealing with more than one replacement and contamination, you have to replace all these.

If the shop had a hot cooler line flusher, maybe save?

For me, $6000 - $15000 trans?

I am going to replace them all.

Sorry for the late reply.

We replaced all lines and even upgraded the trans cooler to Mishimoto when we installed the new trans.

Temps float between 150-160, so I do not believe it's overheating.

Here's an update on my situation: I'm now on my third warranty, and this one is also leaking.

This one reached 2000 miles before I noticed drops of trans fluid on the driveway. It's pooling fluid right at the inspection removal plate underneath the converter.

I'm unsure if it's seal-related or if there is another pinhole in the converter weld.

What makes it even more discouraging is I'm not even beating on the truck; I've been driving extra light and haven't even towed.

I think, at this point, I'm sending this unit back and trying another brand.

I love the driveability instead of the ATS, but I can't deal with a $15k transmission leaking.

All I read online and on these forums is how great RevMax is; that's why when my ATS fried, I made the investment and picked up their series 850 68RFE, but this has been an absolute nightmare.

Is anyone else experiencing this?

Hello, with multiple returns, I would have figured that a different trans sent back to you would have cured this issue.

With the same trans returned, I would suspect a cracked case, porosity hole, or mis-machined area. if Not new with trans Also have seen bent flex-plate causing flexing of TQ and premature bushing wear.

I would suggest somewhere on the unit to stamp you out to identify to see if they just sent back the same unit.

Sorry for having such difficulties.

At this point, I would have a reputable trans shop examine and with bore scope pictures going forward.

At the dealership level, we use dye trace to detect fluid leaks in oil-trans-AC systems.

Your description should be easy to pinpoint.

The TQ Converter weld leak would be a huge leak while running and spraying around the front of the trans, with the leakage noted while sitting, and as the level is draining back to the sump and raising, then a front cover seal or TQ front seal would

Inspection, spraying, drying with cleaner, and retesting for fluid reappearing are the only test methods.
