Want this question answered?
No
No it will NOT interchange. The 350 and 400 turbo are actually VERY different transmissions.
If it has overdrive, then it is the 4L60 which is almost identical to the earlier 700R4. If it does not have overdrive, then you most likely have the Turbo 400 3 speed automatic.
There's only one type of 400 turbo.
i need an exploded view of a turbo 400 transmission? there is a site with trans schematics tcsproducts.com
the 400 turbo is made for more pulling that's whats in my 85 gmc 2500 its just a heavy very expensive transmission.
the older style turbo 400 has a point on one side of the pan in back of the transmission
The 350 turbo is a good transmission but the 400 turbo will take more abuse.
No. 2 and 4-wheel drive transmissions are different. Will not interchange.
yea u can,
That should be a 400 TURBO.
