is it worth rebuilding a th400 yourself
I have a 76 cj7 with a 304, th400, and a quadratrack. When I first bought it, it was pushing tranny fluid out of the dipstick tube. I cleaned out the vent tube and it helped but didn't fix the problem. The whole time the transmission has been slipping during initial take off and shifting kind of funny for a while. It seemed to shift pretty solid but occassionally just driving down the road it would down shift for a second and then upshift. The last time I tried to drive it, I put it in reverse and it kind of started to roll backwards, then I put it in drive an it wouldn't move, then it wouldn't move in any gear, it was like it was in nuetral. I checked the fluid level, it was good.
1) is the transmission dead
2)is it worth rebuilding myself or just paying someone. I'm fairly mechanically inclined but never attempted a tranny rebuild. The cost of a rebuild kit (from autozone), torque converter, fluid, set of retainer clip pliers, repair manual, and a clutch spring compressor tool is about $500. I got a quote from a tranny shop for a rebuild is about $900 (I'm stationed in Hawaii, every thing's expensive). I wonder if the extra $400 is worth the peace of mind that the work is done by someone with experience.
Since I've never done it I know there's going to be a lot of little things I wouldn't know to check or to watch out for.
