S 10 4X4 Question

None of em' except tranny's originally attached to a 2.8. The 2.8 has a different bolt pattern than the 4.3 and SB's, hence the TH350, TH400, TH700R4 off of other vehix won't bolt up.

I don't believe they are year specific............

Doc

wiring in the pan changed between 85 and 86

changes are:

pre-86, TC solenoid is fed voltage thru brake switch to solenoid, which had other end grounded

putting a pre 86 transmission in an 86-up vehicle will cause immediate lock-up upon shift to 2nd gear

"> wiring in the pan changed between 85 and 86

Also unless I am mistaken, the V6 60degree engines have their own bolt pattern (as doc said) so he can ONLY look at 2.8L beasts, as well as now he has too look at years. Make sure to find out the year of the tranny, not the vehicle. Just because it's in there doesn't mean it's the right year, or wired correctly.

a bit more info:

there is a code stamped into the pan mounting rail, right side near the back

such as 5TK206A

the first number refers to the build year the next two letters (three after 86) indicate what vehicle it was in, this determins wiring in pan next three numbers are Julian date........day of the year last number is shift it was built on

so if you have a '5TK', you want to keep a 5TK in there
