On car Forums there always talk and speculation about upgrading engines.
fitting a Coyote is a popular one, but the cost and complexity often rules it out. What about a trans upgrade there are a few used ZF 8 speeds from Jeeps & BMWs etc available now. and would cost much less than an engine upgrade are they generic enough to fit to a Falcon or Territory bell housings mounts removal of 4WD? would the cars ECU just accept the change bottom line is it worth it? probably not. but interested to hear if its possible

The 8 Speed seems to be quite versatile too

One story I heard was locally Ford took the calibration settings from a BMW ZF 6 speed auto when they first starting working on the program to fit it locally and then started their own development. I guess with enough money anything can be done however the physical installation might me the least troublesome part and rather getting the electronics to work together between car and transmission. |

Better off using the 10R80. Already used behind the Coyote, and the 3 litre powerstroke that is pretty similar to the 2.7 in Territory. I think you can already buy trans controllers for them to run it.

sounds good, but I just thought being new they weren't readily available at a good price

I recently got a factory rebuilt ZF.
It was built to order, and ZF were very particular about getting the serial number and software versions, to ensure it was correct, and correctly programmed for my car. Now Obviously "anything is possible" if you're prepared to customise enough components, but I think it's clear that these things are not "plug'n'play". I tend to think that if something was available as a factory option, even in a different car, then the parts should be available to make it work. But I don't know how you'd go installing an engine and transmission combo that was never sold. And then how do you make it work with the tc & esc in your car. I love watching the tv shows like "Banger Races" and "scrapheap challenge," etc. And some of the things they come up with are truly astonishing. But in a recent one, they transplanted a Jaguar V8 and transmission into a smaller vehicle. The Jg had seven different computer modules, and they brought across everything, including the entire Jag wiring loom. And they just couldn't make it work. It seemed to run fine, but everytime they put the foot down, it would cut the power and wouldn't rev. If all the computers were programmable, or replaced with ones that were, and you knew enough to reprogram them, then in theory you could make anything work, but that's a lot of big ifs. And why? I think autos are a bit like razors (and toothbrushes). Yes, the old cut-throats were a bit iffy, and even the original singles weren't great. But do I really need 5 blades and a track-ball to have a shave? I'm sure 8 gears is better than 6, but how much better? And does that justify the expense? |

I imagine we would have been having the same discussions 30 years ago about how complex 4L60E/4L80E were with their electronics compared to TH700/TH400 autos at the time being mechanically controlled.
Now we're having the same discussions about how complex ZF6/8/10 are compared to early 4sp electronically controlled autos ![]() GM seems to really support their product in the aftermarket, you can buy their new engines and transmissions with control packages for retrofit into older cars, Ford seems to lag a little behind with supporting their product in the aftermarket, they do release them eventually but it's not promoted as heavily. |

This guy from Diablo explains some of the issues they had to help Gas Monkey put a modern Hellcat Motor into a Dart. I would say the trans change would be the same.

It's been annoying me forever because commos use the exact same getrag manuals as BMW but there's zero chance getting one onto my old BMWs - because ZF or getrag ie the germans, don't believe in separate bellhousings. If you want trans upgrades forget the germans. E: I miss the old days when you could just bolt on a bell housing onto a celica 5spd etc Last edited by oldel; 28-07-2021 at 09:31 PM. |

Spoke too soon, can already (for $500) get an adapter plate to throw a 8spd zf behind one of my 1990s bmws
https://pmcmotorsport.eu/product-eng...-Vertical.html Getting it to fit in the tunnel and to even work is another issue entirely as stated by others. |

im sorting an aode 4 speed od trans for a big block bell pattern and JW ultra bell supplies one
the aode is all one piece including bell and you cur this off and their kit is bolt on all instructions provided maybe they do one for your situation too the only thing i have to change to accept the mod is a smaller dia torque converter to suit the bell https://racewithjw.com/product-categ...ra-components/ cheers

Remember, amateurs built the Ark...Professionals built the Titanic! I have taken up meditation... at least it's better than sitting around doing nothing !! |

A video for those interested.
https://www.youtube.com/watch?v=u0BZ...ist=WL&index=7 And from experience moving up from a ZF6 to a ZF8, it is a massive leap. They are tuned to be almost as aggressive as a DSG on upshifts in the Raciest drive mode. More gears also = closer gearing = more time in powerband = much more response. 7th and 8th only come into play at 110km/h cruising anyway.

Not to mention the cost.. im on another forum with a couple of trans gurus including one who developed one of the first transbrakes (and sells one of the best brakes out there today) and he still runs a transmission shop, and they say the cost of rebuilding the new stuff is very high at the moment. Ford however is selling an ECU to run the 7.3 and 10 speed auto. Cant see the factory ECU of a car with less gears from the factory running a newer box with more gears by the way, not without custom operating software created. Youd need to flash a manual gearbox program in and run a stand alone transmission controller, that would be the most viable option. There are stand alone controllers for 4l80e's , they can also be converted to 6 speeds by activating the over drive in every gear (1st, 1st OD, 2nd, 2nd OD, 3rd, 3rd OD) More gears are beneficial for less hp/torque vehicles, the more power you have the less beneficial it is, and starts going backwards in the real world due to wheelspin as hp increases unless you have a good traction control system in place... and when traction control is limiting power... well less gear would be just as quick. High stall converters with lock up do wonders also which is probably another reason multi speed controllers havent taken off. You get the best of both worlds with those and theyre quite common now for the Ford and GM overdrive transmissions... they will also keep the rpms high when youre on it, but provide the economy and low rpms when cruising... and the AOD and GM boxes are waaaay less expensive to buy and maintain/rebuild. |

Another issue is that if the engine and transmission controller arent in synch, (ie the car isnt a factory multi speed auto)... power cant be momentarily reduced on shifts and that will kill some of the multi speed boxes behind powerful/modified engines. This isnt a problem with the 4l80e because with a few mods they hold 1000hp plus easily and full power on shifts. I dont think people are afraid of the complexity of the multi speed boxes, as people are used to the older electronic trans from GM and Ford now.... theyre afraid of the rebuild costs. ![]() In terms of controllers if you can make one for a 4l60/80e you can do it for the other ones, but because of the cost of the boxes, and the ease of power adding to engines these days, there doesnt seem to be a huge demand yet, at least in the places i look... the US based mainstream aftermarket performance companies. |

With an 8-speed box, it's pointless unless you can reprogram the box to suit your engine and car. But the big challenge now seems to be the level of integration, particularly with traction control and stability control. People love transplanting Barras into older cars, so I imagine those computers are relatively independent. You can drop the Barra in and it doesn't care that it's nolonger in an FG. But with more modern cars, without full integration and feedback with all the systems, the engine and tranny either won't run, or go into limp mode. Modern traction control seems to be the biggest issue, with all the sensors. Again, simpler systems you could just turn the TC off, so running it without TC shouldn't be an issue, but modern systems are never really completely off.

when I jump in my Territory after our BMW, its the gear changes that I miss the most. The ZF8 really is that good, and from that video it shows how many cars have them. Interesting new BMWs haven't transitioned to the 10 speed

What you linked to is for running the 8 speed with an LT1 engine. Those controllers for engine and trans are pretty much the same ECU as whats in the production cars, which can be tuned with HP tuners... GM turns the stuff not required or wanted off for these controllers ( like VATS for example) ... which is what someone at home can do with LS/LT computers taken from late model cars to install into other cars.. when they have the software (HP tuners or equivalent) It might be possible to put those GM ECU's and the sensors destined for an LT1 engine onto another engine just to be able to run the transmission behind it.. but things start getting tricky as the LT is direct injection, one would have to turn off a lot of fault codes and checks and get creative, if its even possible. I know you can turn off codes and whack a carby straight onto an LS1 car and it will run right with the ECU still doing the spark and transmission, but I havent messed with LT1's to see what is possible because we didnt get those here in numbers, other than the odd import thats been converted. Ive seen GM 411 (LS1) PCMs adapted to windsors, and then they will run a 4l60e and 80e.. whether that can be done with the newer LT1 ECUs, to run a different engine, i havent seen anyone do it yet. Ive even seen 454 chevys and 440 mopars running the GM 411 PCM and converted to efi. They add the GM cam and crank sensor to the other engines, and the coil packs. Those too can then run a 4l80e (or a 4l60e if you like breaking things ![]() Last edited by lumen8; 29-07-2021 at 02:57 PM. |

It would be easier to do use this with a late model vehicle that has a manual gearbox, or flash a manual tune into it or swap to a manual ecu (if an auto), if said vehicle came with a manual option. Then the car thinks it has a manual gearbox, and that aftermarket computer can run the transmission. Keeping the two separate is much easier than the other way around. Kind of the same as running older race autos in late model cars...change the tune to a manual file, and the transmission works standalone without freaking out the cars tune and the engine behaviour. But in the case of the 8 speed another ECU will run that. |

Theres a lot of youtube clips using the HTG & ZF8
an MX5 even has the BMW shifter, look how well it shifts!! https://www.youtube.com/watch?v=mJdpzyEKY1Q

![]() I think an 8 speed is probably the best compromise between having enough gears for economy, and not being a pain by hunting for for the right gear.
