Hello, I have a bit of a project truck I just purchased. It is a 1988 Nissan with a '95 5.0L with little mods (port/polish stock heads with 600 cfm Holley and highrise intake). Truck runs excellent and just got the carb set up. The trans also has a Stage 2 shift kit. But under full throttle it wants to shift from 1st to 2nd at 4000 Rpm, 2nd to 3rd at 3500 Rpm and 4th at 3200 Rpm. I've tried adjusting the TV cable from one extreme to the other and all the places in between, with no better of a result.. Seems like the only way to really get any performance out of the trans is to manually shift from 1st to 2nd and so on. I dont want to goto a slap shift/manual shift kit..any suggestions of where to go from here?
