International Coal Roller
So I have a 2002 with a ZF6, soon after I bought it I changed all the fluids over to synthetic, put mobil1 ATF in my tranny and as soon as I changed it I started to have issues. The PO couldnt tell what fluid was in it, all he could tell me was "whatever Les Schaub puts in" so he was no help there. Whenever I try to down shift from 5th to 4th it want to grind just a little unless I slam it in, seems like the synchros arent working right, but only in that particular shift. Since this issue immediately started after the fluid change, and not before it leads me to think that the fluid is to blame, and it is a PIA especially when towing. I was reading up on some posts on here and saw one about using Amsoil MTF or MTG instead of ATF. I was wondering if it would be a good idea to change the fluid over to Amsoil, and if so which one, or can I mix MTF and MTG, when to change, etc. Its annoying, and Im scared Im gonna tear up the tranny or the synchros if it keeps on as I dont have the money to fix a tranny right now as Im about to PCS across the country. Sorry for the long post and thanx in advance.
