Yeah bad oil. It was approved for the ZF but I guess it has problems. Also I did fill it up properly. get it to 30-40c. Then go through park, reverse, drive, second gear and then back to park. Then filled it while still running. I never took off the oil pan, and only topped it up with that Penrite with around a litre after the oil cooler. I did check the oil a few weeks after, and I could put in another 200-400mls until it started seeping out again. The bad thing is it got worse after around 2 weeks, it started off slightly slipping going into 4th, now it will not at all even after being off throttle for 10 seconds and then letting it idle trying to grab that clutch. One really weird note to mention, once it was in 4th gear shifting to 5 and 6 was fine, which makes sense with the way the E clutch is used. But even under high load around 400kw in 4th gear it wouldn't slip at all. The only time it ever slipped was going from 3rd to 4th. I feel like the trans is done in its current form, in my opinion.

The trans slips trying to go into 4, 5 or 6 and fails every time now. I think it's the E clutch worn out? I used Penrite BMV after installing an external trans cooler and it started happening a few weeks later. PS. The old standard heat exchanger never milkshaked so it cant be water that caused the issue.

Hey, I'm currently putting a NA FG ZF into my Turbo FGX. (Just so I can drive around for now) I'm using version 2.11 and I tried writing to the trans and it came up with the merge dialog. Then once it was done and I power cycled the car it shows Transmission fault on the dashboard. I'm not too sure how to continue. From my understanding you cant change the TCM over as the turbo trans is the first gen ZF, and the NA trans is a second gen ZF.

Hey, I thought I'd also make this thread, similar to the one I just created but for the 6R80 transmission. I was wondering if it would be possible to swap a Ford 6R80 into a Falcon. The TCM would need to be swapped over from the current ZF to the new 6R80. Would swapping the TCM even be possible? Are the bell housings different? Are the torque converters different? Thanks, Dylan.

Hey, I was wondering if it would be possible to swap a ZF 6HP26 or even a 6HP32 from a BMW into a Falcon. The TCM would definitely need to be swapped over from the current car to the new one. It's got a 6HP26 as stock at the moment. Has anyone done this or have any experience with these transmissions? Are the bell housings different? Are the torque converters different? Is there any major differences internally? Thanks, Dylan.

It only started slipping a month after topping up the fluid. It could’ve been on its way out before that but I never data logged anything major trans related before then. Yeah I defs will while I’m there.

Haha, I’ll have to look at that if I take the box apart, I do want to try ‘fix’ it for now with it together if possible. I haven’t played with the pressures at all, nor have I checked the pressure vs target. I will need to check them. I’ve had these trans changes for over 2 years so far without issues, I think I’ll try increasing tq reduction timing and the main shift pressures and see where that leads me. Would changing the fluid help me at this point?

I’ve made the shifts slightly faster and made the converter lockup in 2nd a lot sooner, around 1k rpm. I’m not sure if it has a leak, what 3 seals are you referring to?

Hey guys, Just looking through this thread as my ZF has started slipping 3-4 and clutch e is maxing out adapts. I recently changed my trans cooler and topped up with Penrite BMV. Is my trans cooked now or would changing the oil to lifeguard or gulf western potentially fix the issue?

Count me in 3!

I'll give that a try, fingers crossed

These are my torque requestor tables, I haven't changed them from stock

Hey mate, Thanks so much for your input but I've been playing around with that on the weekend and it still wont fix the problem. It will do the injector cut 90% of the time, but that 10% at high load usually only from 2nd to 3rd it still wont happen. I even played around with setting auF11392 to 0, 1000, 2000, 3000. That didn't do anything at all. I reduced the torque reduction a bit and set auF11857 to a lower torque number, 150-200. This still didn't make a difference. I thought that would've done it as the datalog it shows the torque at flywheel (TQE_BRK) shows under the value in auF11857. I thought that maybe the normal torque reduction was reducing the torque below the limit auF11857 and that wouldn't trigger the cylinder cut. I've gotta be completely missing something here, I'm not sure what though.

I'm not sure if I should put this in Engine Tuning or Transmission Tuning but I'm just gonna put it here. I've got a FG X XR6 Turbo, when I am on full throttle and above 18 psi or so and change gears, sometimes the injector cut (golf farts) won't occur and this causes my boost to spike like crazy after checking the datalogs. I'm not sure why this is occurring, my only theory is that the engine torque that gets sent to the transmission is below the threshold set in auF11857 - Tq_brk_s_str limit below which no injector cut is allowed during ZF gear shift. If anyone has had this issue or might have an idea on how to fix it, it would be greatly appreciated.

How tf did it handle over 700 kw at all, I'm actually amazed. I guess you had a lot of mechanical sympathy. That thread is a good read thanks for sharing! Hopefully you get it back on the road soon!
