I am looking at rebuilding my transmission (its the 4T60E) on my 1995 Buick Regal 3.8L and am wondering if I should get the ATSG Transmission Repair Rebuild Service Manual. I haven’t heard of ATSG before but the transmission manual was recommended to me. I have the service factory manual for the car and am not certain if the ATSG manual will have more or better info. I have never rebuilt a transmission before so this will be my first. I am not opposed to spending money on the manual, I just want to make sure I am getting something worth my 30 dollars that will help.
