Default 700r transmission

Hi,
I'm new here, I own a 1989 full size blazer with the 700r transmission. Unfortunately the tranny is about shot... could someone tell me what model years had the 700r tranny?
Thanks

The full size Blazer and the S-10 Blazer are not the Same. The Bell housing are Smaller on the S-10. Also Make sure you have a 4x4 or 2wd ? As they have a different Tailshafts. As you did not say what you have in yours?

Must use the Full Size Blazer or Full Size Truck or Suburban 700r4. 1987-89 on the Burbs. Hope this Helps? Good Luck

You really should be looking for a trans from a 87 thru mid-92 v8 vehicle with the same drivetrain configuration (4wd or 2wd) as your vehicle. There were improvements made to the 700R4 in '87 IIRC.

That all depends on what engine the s-series truck came with. If the trans was behind the 4.3L, the bell housing is identical to the v8. The transmission isn't built as strong, but it will bolt up to a v8 without issue.

Sure, it would bolt up to the engine, however, either would require changing the transmission & transfer case mount locations, driveshaft lengths, and even then, the transfer case (if 4wd) may not bolt up to the back...

BTW, the 700R4 can be built just as strong as a TH350 and the TH400 is overkill behind a small block. Not to mention it is not as efficient as either the 700R4 or TH350. Also, if it is a daily driven truck, OD is nice.

yeah the overdrive is a plus if its a daily driver, i was thinking the actual casing being stronger, cast iron over aluminum, idk that much about the gear setup, just thought i squeak in my 2 cents if he was looking to upgrade

You do realize that all of the transmissions you mentioned have aluminum cases right...? And the K case used on the later 700R4 is VERY strong. Hope you provide change...
