i would guess so if you wanted to bad enough but generally no, and most all transmission shops will probably say no also. In the Overdrive catagory you have a fare selection of OD trnsmissions that have different ratios. Well actually three that I know of. The 200R4, 700R4 and the very expensive 4L80e. Each offer a different gear ratio and each have their strengths and weaknesses. Well not the 4L80e I don't know if it having a weakness at all other than the outragous cost of installing and running one.guru54 said:i know he was talking rearend but i was just wondering if u can switch the transmissions gear.
