I was snow wheeling this weekend and smoked my th350. What’s the trick to keep these things happy in the snow. Yes my trans cooler probably needs to be bigger. I was running a 4.3 vortec 2.28 case 5.29 diff and 37s at about 3000-3500rpm in 3rd gear and it would run about 220temp and then I’d stop and let it cool off and eventually it shit the bed. Reverse and 3rd are barely hanging on 1st and 2nd are strong still. I noticed if I run my 4.7 case and 3rd gear it runs cooler but then I’m slower and higher in the rpms.
