Isuzu Trooper Owners Club UK™

[Robert Filbry]

Hello mates,I am having problems with my Honda Horizon badged Isuzu trooper /Bighorn,owned for 10 yrs down here in Tortola British Virgin Islands ,no problems previoustly ,use low gear to descend hills ,recently gearbox wouldnt go into any gear but second , low- drive all give me second as she moves off from a stop slowly,reverse has full power ,trailered her home and changed tranny oil /filter checked all solenoids in valve body all appear good ,filled her up with fresh oil and tried again ,no change , found I can still drive up hills using low range 4wheel drive, nasty on dry roads. will try to read transmission codes ,I believe it is fitted with the Asin Warner AW30-40LE box although no numbers on the box except casting #ASIN 8980 10   The body plate states Trans RMD Grade RBL whatever that means .Will try to obtain trans codes then start looking for parts or a rebuild shop. Anyone with advice would be appreciated ,no one on island knows these vehicles
