im trying to get my esi back on the road. but im having trouble deciding on what gear oil to put in my tranny. ive read to use ATF+4 or pennz syncromesh. But im not to sure about using either one on this Chrysler tranny..

but what do u guys think about using redline gear oil product. has anyone used it before?
this is the only thing holding me back after having my esi parked since 2005...
