hi I have a 80 series 12v 93 auto done a few jobs since getting it radiator cooler for gearbox gearbox oil renewal and rebuilt the front wheel bearings and oils seals up to the front diff after the bearing collapsed and it all welded itself together not the greatest start but we are up and running again would like to come to some of the meets if possible for fun and to improve my truck live near rugby still having a little trouble with overheating the gearbox oil when heavy toward a 16 foot Bateson and 2 ton on the trailer so any help appreciated it was much better with the aux cooler fitted but did not like the big pull up the hills on the m1 South at Leicester overheated again pulled over and cooled it down and trundled home but was worried to death however no damage done but would like to improve things all other gauges were fine on overheating on the engine any advise appreciated regards Jt
