Searched for this one and although I'm fuzzy on my viper info I don't recall seeing this one come up before and was hoping someone could provide some insight.
Went to go for a drive today, goes into 1st, 3rd, 5th and reverse fine. Car will not stay in 2nd, 4th, or 6th regarless if the car is moving or not and the gear is under load.
If you try and put the trans into 2nd at a standstill, it will pop back into neutral and the shifter will center itself. If I hold the shifter in 2nd, it will engage the gear and drive normally.
The car is never beaten on and was put away for the winter working 100%. This issue has surfaced now on the first attempted drive of the season.
Thanks. Here's a bonus pic of the winning Comp Coupe from todays WC GT race.
