Raven9 Posted March 19 Share Posted March 19 78 R686, with the TRXL107 5x5. My Aux box is getting tough to get in and out of Reverse and Direct, I never use low. My question is, Would and Fro bolt up? Has anyone done a trans swap in one of theses trucks, I know ill have to change driveline, and other things, just wanting to get a 10spd in there and something I can get parts for in the future. I haul asphalt so a 10 or 13 would be the cats "meow" lol . It has a brand new motor in it so I really don't want to sell it and buy something else I know nothing about. Thank you in advance for your replies. Quote Link to comment https://www.bigmacktrucks.com/topic/75300-transmissioin-swap/ Share on other sites More sharing options...
