Hi everyone, i have been having issues with a 2nd gear grind in my 97 trooper, and i am planning on changing the manual transmission fluid pretty soon. The only problem is i am not sure which transmission fluid to use
. The manual says to use motor oil but would it be okay to use Pennzoil Synchromesh or even the honda mtf??? since honda use to work together with isuzu. Any information would be much appreciated.
