the 1-2 shift in my blazer has started slipping lately. i had the trans rebuild by my local trans guy that built the trans (c4) in the mustang (both the 700 and the c4 are about 3 years old) . the c4 trans has held up, he said the 700s just get soft and wear out. right now the truck has 3.08s in it. i've been thinking of either keeping the 3.08s and putting a th400 (but i cant find a trans to transfer case adapter, but thats another story) or putting 3.73s in and keeping the 700. i have 31" tires on it. please give me your opinions. thanks. 93 mustang gt- turbo technology street kit 440 rear wheel hp 82 k5, 6.2 diesel, 4x4, banks sidewinder turbo kit- enough power to tow the mustang.
