After building my motor I wondered how long the trans would last since it is just a gmax alto kit with all the Mike L springs. Today I took the truck out for a couple test runs. After the second one as I went to stop the back tires chirped. Went to baby it home and when I got close to home the trans would lock up instantly in Drive. Had Reverse but no forward. Through the P0700 code on my cs. Cleared it and nothing. Coasting down the hill it even locked up the rear wheels in neutral. Must have some welded clutches. Could not get codes cause they did come back after I cleared them. Time to let a pro build it.
