E maxx transmission problem!

[Will26]

I received an e maxx in a trade yesterday, it's the early 3906 model. It has twin Titan motors and the traxxas/Novak EVX. This morning I was running it with two 7 cell batteries then it stopped moving. The motors rev and turn the big center gear that goes into the transmission. The axles don't turn though. Ideas?

Just pull the trans and open it up and if nothing is wrong just grease it.

May have sheared a pin for the primary drive gear. Easy fix but a pain to get apart
