My 93 Typhoon with 22,000 miles on it is not shifting until I hit high RPMs. I drove it last night about 30 miles it run and shifted fine. Today after work I got it washed drove it for about 10 miles it ran great. Did a couple boost launches drove it for about 10 more miles then came home it sat for about 2 hours. Drove it to a dinner it wound not shift unless I went to a high RPM like 4000 to 4500. What makes our truck shift? I had a new turbo, injectors, fuel pump, exhaust, vacuum lines, EGR delete, and a TT chip install about a week ago no problems until today. I hope to make the Carlisle show.
