1969 to 1980 TH350 transmissions. Combo Kit comes with parts we use in our level 3 TH350 Raptor transmission
#K350L3. Fits all 1969 to 1980 GM Turbo 350 transmissions. This Combo Kit comes with all of the parts we use in our level 3 TH350 Mega Raptor transmission. The level 3 TH350 Combo Kit is good for motors up to 600 horse power. This transmission comes with our #8 ten inch torque converter rated at 600 horse power. It comes with 2 balloon plates to prevent converter ballooning, a black carbon fiber intermediate band for more holding power, an Alto Red Eagle master rebuild kit with red clutches and Kolene steels, a high performance Fairbanks TransAction Shift Kit. The low / reverse roller clutch is replaced with a much larger late model 700R4 roller clutch. We replaced the intermediate roller clutch with a much larger 36 element sprag and drum, this is the main weak point on the TH350 transmission. Plus you get a free PATC shirt. There’s a 10% discount on this level 3 TH350 Combo Kit.
