100 Series LX470 8HP swap

So the little off-topic VSS code is after looking through another thread the two reasons you could have a P0500 CEL are that the transfer case vehicle speed sensor is faulty or that you are cluster is failing due to age. The combo meter could have a discrepancy between it and the VSS leading to the code. I also just figured that I would have my cluster refreshed anyway.

I’m probably going to grab the LUTZ speedo corrector once I get back home and that is probably what’s going to give the speed sensor input to the turbolamik, I already got the map sensor I needed so I will need a pigtail harness for that and some new vacuum lines so I can plumb it in.

Hi guys,

The starter bolts present an issue for sure. The Adamat version “doesn’t appear” to allow starter removal either. Is the smaller bell housing version a good option, or does this compromise something else?

The N57 bell housing pattern is the 8hp communities first choice for eight speed swaps. It’s an I6 bell housing and fits in a lot of cars and you got the M57 diesel having the 70 transmission to handle higher torque though people have built 8hp50 transmissions to handle a good amount of power.
It’s just unfortunate that there’s a very narrow range of n57 pattern transmissions in the US being mostly diesel X5s and a handful of diesel 5 series

“N63 8hp70 w/adapter 27.1875" Forgove me, that’s the BMW all wheel drive trans? With the thinner Domiworks BMW to Toyota Transfer case adapter is only 3/8 longer than stock Toyota a343? Am I understanding that correctly? Yeah 3/8 months is not much at all. With the engine adapter on it or need to add the thickness with engine adapter that is another 20mm?

Sorry just want to understand this and make informed decisions.

The dodge 8HP Domiworks claimed with the Dodge to Toyota adapter was pushing nearly 2.8 inches longer.

From Domniworks



787 mm 30.98 inches ! Compared to 27 3/16

Just now seeing this, the reasoning on why the adapter is thicker: the ram/dodge 4x4/awd transmissions have the thicker adapter due to the output shaft/tail section isn't a flat plane like the bmw
RAM trans

BMW trans

The benefit of the BMW is it's shorter overall stack but you need to replace the input shaft on the case vs the ram adapter could theoretically work on a 93-02 transfer case with the A343F 4 speed as the dodge adapter uses a spud shaft.
