I'm just not sure why you would come in here with an attitude like that. There's enough Gen 2 guys who think it's the best thing since sliced bread. Everyone who owns a Gen 2 seems to think guys who own Gen 1's are just too poor to afford them. Either way yes, I know how the 4A works, and how AWD in general works. My shop specializes in European vehicles. The way you word it just makes it sound like the Gen 1 is a shitbox.
Honestly, the reason gen 1 owners don't want the gen 2 is because of the v8 and the looks, it is so much more advanced with electronics, but most of us just love our v8's and we paid a lot for our gen 1's also and it doesn't seem worth the upgrade. Now the Gen 3 looks so much better but still the same motor, maybe the R (if it happens) will have a nice v8, who knows.
I also didn't notice @GCATX him coming across as a know it all, but we all read post differently.

I like them both. I didn't mean to come on with an attitude. Just pointing out that I would prefer the Gen 1 to have 4a and gave my reason. It would give me better peace of mind when the kid drives in the rain.

I'll go back to my safe space now and cuddle my support pony. :cool:

Ok so stumbled on something that may throw a wrench into the swap for you purebreds. Fords Website advertises some of the control modules for the TCs to specifically call out “without hill descent” and “without off-road mode.” The TOD module does not specifically call out a “with” or “without” these features, so it’s hard to say what compatibility will look like. SVT raptors are listed in the compatible vehicle sections for the TOD module. Just no clear indication on those other features. Perhaps those are also just pass through features and will plug right in like mine did?

I’m not sure whether or not the 4x4 module controls this functions. Hopefully the guy that already ordered parts can test out to confirm for sure.

Sure, I'd take the 4A transfer case if it works without losing any other features, especially if it allows for the Gen 2 one to work.

If by safe space you mean garage and support pony you mean support beer then I'm in.

I found this very helpful explanation on another forum describing the differences between the 2015+ Lariat TOD vs Gen 2 Raptor TOD. I believe the TODs that would be available for 2012-2014 are described below as the “non-mechanical” TOD below. The mechanical locking feature was probably not introduced as an option until the 2017+ Raptors so it seems to explain why Ford did not put the TOD in Gen 1. Though, I suspect most wouldn’t ever encounter such extreme off-roading where the locking mechanism described and drawbacks from extreme off-roading would ever make a significant difference..

My pavement queen certainly won’t. :gr_grin:


The difference between the two types of case is that the Hi-Lock (or mechanical locking) TOD case uses a mechanical dog clutch to lock the two driveshafts together in 4Hi or 4Low, forcing them to rotate at the same speed regardless of the distribution of torque.

In essence, the Hi-Lock case behaves like an ESOF case in all modes but 4A, and then like the regular TOD case in 4A.

The TOD cases use a clutch (I believe a viscous clutch) to run in 4A, and simply modulate the engagement of the clutch to increase or decrease the amount of torque delivered to the front axle.

The non mechanical-locking cases simply apply maximum engagement to the clutch for 4Hi and 4Low, and thus the driveshafts are not truly mechanically locked.

In most cases this isnt an issue, but in more severe off-road conditions the front driveshaft can still slip relative to the rear in 4Hi and 4Low, and this can either overheat or overwhelm the clutch altogether. For example, if you're stuck in deep sand or deep mud, it's possible that the front wheels may not even spin if the torque required to spin the front driveshaft exceeds what the clutch can give.

The cases with the mechanical dog clutch are more capable of delivering that torque to the front axle. Instead of being limited in the amount of torque it can apply to the front driveshaft, it can provide up to 100% of the torque to the front in 4Hi and 4Low with zero slippage. So if you get hopelessly stuck, you can spin both the front and the rear axles up to the point you grenade a differential or something.

Something that has not been addressed is the IWEs, the gen 2 IWE vac system was redesigned a little to accommodate the auto transfer case and does some different things at start up and the gen 2s have more problems with the system loosing vac. That said I don't see why auto TC would not work on a gen 1.

@CoronaRaptor as far as the electronics being more advanced on a gen 2, you make me laugh. The gen 1 is far more customizable than the gen 2 ever thought about. Ford made canned settings so the gen 2 would be easier to setup for conditions. I still want to see a gen 2 lock the e-locker in 2 wheel drive and have it stay engaged past 25 MPH. I rest my case.

I meant the truck overall is more advanced, not just mechanically, I'm still a Gen 1 fanboy so don't worry.
