I have a 98 GP GTP with 76,XXX. I recently put in a custom FWI and it made a huge difference, but I just started getting hard shift between 1st and 2nd. Seems like it is slipping and then engaging hard. revs to 5K+ before shifting hard. Tranny filter and fluid change @ 73,xxx, plugs and wires last weekend. Fluid level fine, no black or burnt smell and there was no metal in the pan when fluid was replaced. Any suggestions???????

Welcome to AF!!

Sounds like the pressure control solenoid in the transmission. About a $500 repair at a tranny shop. Take it to a tranny shop or someone with a trans capable scanner and have them scan the trans computer. It will tell you what is happening.
