Hey guys I have a 1000 in my race car and I have a few questions.
1 can some one tell me what year this motor is from the vin (Sc57E2102810)

2 I’m having an issue with it jumping out of gear at first it was just second gear. But it now it doesn’t matter what gear. Keep in mind highest gear i run is 3rd at any given time

 

Welcome to the forum, looks like it is an 01 engine
Could be gear selector fork issues.
SC57E is model number
2 is a random check digit
1 is year
0 is plant it was manufactured in
last series is production number

 

Jumping out of gear can be from several sources:

1. worn-out gear-dogs. Can typically fix by back-cutting the dogs so they pull gears together under load

2. worn-out input & output shaft bearings. This causes shafts to be non-parallel. Gear-teeth then engages at angle. This angle pushes gears apart under load.


Either way, you'll have to split engine-cases and take closer look at gearbox.
