I have a TH350 that was overhauled by a friend...I know...but the price was right & he does good work. I have installed it & it works fine but the shift from 1-2 is delayed..not slipping but it continues in first for a second before shifting. I installed a Transgo TH350 1-2 shift kit & the delay is shorter but still there. How do I get an instant shift? My glide' before this shifted instantly but it was built by a trans shop with a Trango Auto-stick kit. Any ideas?
