Wow, that ain't cheap! Anybody gone that route yet?
At $150 a tranny at PicknPull and a steady supply here in California, and never having seen a heat related failure, that would be a lifetime supply for $1,000. Some may be clunkers but most tend to be ok.
I had my trans apart last year to rebuild the LSD and change 5th and after 25+years on the street and 6 race seasons there was almost no wear whatsoever on the ring and pinion, all bearing were tight and within tolerances and even the synchros were ok. Even my two donors are good inside except for a broken ring gear from the kid trying burnouts, and the other is missing its 5th from me crushing the synchro hub!
