Hello fellow malibu lovers. I have a 79 malibu. Just got new bbc fired up today and running. Question is I got a new th350 with a 2800-3200 stall converter. Questions is it. Feels like it just dosent shift right or at all. I have a stock rearend with stock gears. Probably freeway gears. Im gonna be changing asap. Questions is could it be because or my stock sad rear would that be causing me not to shift. I can provide any other info to help. Will be changing to 4:11 asap. I still thought it should shift thru the gears tho. Not sure if its a transmission problem or a rearend to swap first?
