M1083 transmission problems

[Altman63y]

Our fire department has a 1083 that the transmission was just replaced in due to a cracked housing the guy that swapped it put iso 32 hydraulic fluid in it now it will shift fine when cold but after the oil heats up it slips when shifting I have tried to calibrate the shift points and it seemed to help but still not right. Has any else ran iso 32 in the transmission or got any ideas

Drain, fill with atf and try it. If better, drain again, change filters and refill with transynd? aw-32 hydraulic oil(10wt) is most likely NOT meant for something with wet clutches, and it may have destroyed them... Hope you don’t need a new trans... good luck...
