I was wondering if anyone may be able to tell me the approximate speeds that the 700R4 tranny shifts from 1-3 gear. I have an 88 S-10 4.3 and I just installed the replacement Holley TBI and a 1 " Poweraid spacer. I am not sure what the correct speeds are that the tranny should shift. It seems like it shifts a little pre-maturely now? Any input would be great! Thanks.
