I driver about 60,000 miles a year in my 78 2wd blazer. I got sick of using a vehicle that won't fit my sales samples or me very good. I have a 89 4wd Jimmy I've had for about 12 years now and I have always loved K5's. So I was looking for a 2wd in decent shape that I could swap a Fuel Injected motor into. I ended up finding my 78 with a TPI out of a 87 camaro in it. It runs great but it came with a TH350. I swapped in a 700R4 that was suspect and it did not last very long.
I was going to rebuild a spare 700R4 I had laying around but time constraints caused me to look to buy one. I bought a level 2 700R4 from BowTie Overdrives.
It is rated at 450HP and 500FT of Torque. It cost a little under $1800 to be shipped to my door in southern Utah. I got it with the torque converter and the installers kit.
It took me about 4hrs to swap out the old 700R4 and put the new one in, test it, calibrate it, and sign up for the warranty.
It comes with a 1yr unlimited mileage warranty if you set it up like they want you to.
To set it up, you first have to have the correct TV cable etc...
The other main thing they require is to use a pressure gauge hooked up to the pressure port on the side. You go through various steps, recording the pressures as you go. Once they, and you are satisfied, you are good to go.
I cannot say enough how pleased I am with this transmission. It feels like I gained about 75-100 more HP just because the transmission acts like it should. I am now getting 22mpg flat land, and 17mpg going on the 70 through the mountains of Colorado.
If anybody is looking for a transmission, I HIGHLY recommend them. Quality work.
If anyone has any questions, feel free to ask. I did not take any pics as it was all pretty straightforward.
