Are you speaking in regards to the plastic gears or the metal gears on the way? The plastic gears were always properly shimmed (been using the same mesh technique for more that 30 years), but don't seem to be able to stand up to my self modified (all my engines are) 18TZ.
The car doesn't have diffs (direct drive) and the initial hit on a prepped drag surface is too much for the plastic gears. Thanks for the advice.
