New Venture 4500 - SALE- Starting at $1500 E for quote

NV4500 (1993-94): During the first two years of the New Venture 4500, Chevy offered this 5 speed with a 6.34:1 1st gear; 2nd 3.44:1; 3rd 1.71:1; 4th 1:1 ratio, and a 27% overdrive. It was also the first year that Chevy changed the bellhousing-to-transmission bolt pattern. This transmission is ideal when converting your vehicle, providing an ultra-low 1st gear. GM, however, only produced this particular ratio during these years. The major complaint of this 5 speed was stiff shifting and noise in 3rd gear. NV4500 (1995): This transmission is identical to the 1993-94 transmission, except the 1st gear ratio had been changed to 5.61:1; 2nd 3.04:1; 3rd 1.67:1; 4th 1:1 ratio, and a 27% overdrive. The noise and shifting problems had been corrected. NV4500 (1996-2001): This transmission has the same gear ratio as the 1995 version. Chevy once again changed the bellhousing-to-transmission bolt pattern and went to a larger bellhousing index diameter. This Chevy NV4500 has the same bellhousing-to-transmission bolt pattern as the Dodge NV4500. These transmissions use a GM internal release bearing. Dodge NV4500 (1993-2000): This transmission is the same as the 1996-99 Chevy version; however, the only difference is the transmission input shaft, output shaft and the tailhousing. The 2001 Dodge transmission was changed to a 29 spline output shaft. All NV4500 transmissions have a 12.375" case length.
