Hello first time here ill try and get it right. Well I have a 85 k5 blazer with a 350/th350. Yes someone changed it over to the th350. The tranny was leaking out the front seal so I pulled it figured while out put new clutches in the old girl. Put the new kit in now it wont move, It feels like it goes into gear then nothing. I pulled back thought pump was bad put new one in same thing. At high rpms it moves a little. Any ideas?
