I recently bought a 83 blazer with 2.8 and 700r4 trans. seals were leaking so pulled trans and replaced front and real seal along with new filter . put trans back in and now trans will not shift . Have adjusted t.v. cable properly. and have even checked gov. still wont shift. only paid 125.00 for it but it runs excellent and looks decent too. before I pulled it it shifted fine after wont shift .have set t.v. cable correctly!!!! hummmmm
