Help!!! Transmission guys

Postby 99_trooper » Fri May 07, 2021 7:31 pm

Ok, new guy here.
My questions are about transmission. On one of the Facebook Isuzu groups. One of the guys was saying that bell housing on 2.5 & 2.6 are the same as the GM 60° V6, ok. But he also stated that the 3.2 & 3.5 also shared the same 60° V6 bolt pattern. It was also stated that any transmission from a GM 60° V6 will bolt up. I'm still learning my way around this website.

So is this true?

Thanks

There is no "2.5". You may be thinking about the 2.3 and 2.6. Those DO share the same "bell housing" pattern, but it is nothing like a GM 60 degree V-6. It is my understanding that the 3.2 bell housing pattern MAY be the same as the GM 60 degrees. IIRC, there is a place on each side where there are two bolt holes and one set fits the 3.2 and (again IIRC) the other hole fits the GM pattern. Hopefully, someone else can add further details about the GM / 3.2 bell housings. Dennis

The 3.2L & 3.5L Isuzu V6 share the same engine block. these engines fit the GM 60 degree v6 bolt pattern. This pattern is different than the 60 degree 4 cylinder pattern. Thus the 2.3 & 2.6L Isuzu 4 cylinders which share the same engine block & will not bolt to the V6 transmissions.
