Tranny Case/Differental Repair..

admin

Well this was slightly diffrent for a change..This came from the local Cottman Transmission shop.."Newer" Dodge minivan Tranny case..Seems the pin that holds the gears in the chuck got loose and started rubbing its way out...Upon inspection I had determined that what was left of the casting was only about .015 thick..So instead of making a big molten yuck out of it I decided the best remedy would be to loose the rest and make a piece to fit..So it was die grinder and wax time..Off to the stock rack for a piece of 3/4"X3"x1/8" aluminum..Cut..sanded the corners and rubber hammer bent in a vice..So now its tack it in time..Note the black soot from the casting..Just wire brush it off and continue..(Yes i know the top right tack is cracked..so do it over)And we continue on the next post.....zap!Last edited by zapster; 02-02-2007 at 05:04 PM.I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:That is an extremely common failure in those Caravan transmissions.  I'm supprised that a newer one would have failed because that would indicate the problem still hasn't been fixed.
