i have an 07 zzp stage 3 with 93000 miles on it, was getting on the highway, was in 2nd gear, went to shift to 3rd, rpms reved up, than the rpm gauge went to zero, engine still running, everything worked, was going 60 mph, felt like i was in neutrul, put back into 3rd nothing, so i shifted to 5th no problem, rpm gauge still at zero, noticed boost gauge going hay wire, driving fine goin 70 , went to pass a vehicle drop into 3rd nothing, car started hesitating, pulled over to side of highway, shut car off, waiting 5 mins, started up ran fine ever since. No CEL no nothing, what could it be???

thanks in advance

 

Did you et your ignition recall done?

 

according to the dealer i bought it from they said it was done, how do i find out if it was done?

 

GM will have your VIN on file. take it back or to another GM dealer to make sure. they should be able to tell you.

 

Probably something eletrical.
