hello, i have a 85 jimmy with a 700r4 and 208, leaky and sometimes makes strange noises, i belive its getting tired and needs to permently go to sleep. id like a th400 and a 205 but there hard to find around here. but i did find a used th350 with a 203 or 205(i havent checked yet) out of a old 77 1/2 ton truck for 400 bucks. what do you think? is this a decent deal? is it a easy swap? is a th350 stronger than a 700r4? any info would be awesome thanks!!
