Unbrakeable

Donor engine is from a 97 T100 Auto, and I'm hoping to use a 2000 4runner auto behind it. I'm reading that the T100 autos had a different speed sensor on the trans.

"The other obstacle when using the 3.0L A340 in this conversion is the input speed sensor. The sensor in this transmission functions differently than the sensor used in the 3.4L AT applications. While this can be driven, it results in an imperfect shift pattern and continuous trouble code. The exception to this problem is a T100 application, where the 3.4L transmission used the same sensor type as the 3.0L A340 transmission. For this reason, using a T100 donor application (or at least the ECU) will result in perfect shifting and no trouble codes when using the 3.0L A340."

From what I'm understanding, I'd either be further ahead to get a 3.0 auto or to find an auto 4 runner ECU? Initially my first thought was to just swap in a t100 sensor but will this cause the transmission to shift imperfectly?

Hopefully its as simple as sourcing a auto 3.4 ECU thats not from a T100 and plug and play, but things never work out that easily.
