If your KTM 250SX is blowing transmission oil out of the vent hose, it could be due to overfilling the transmission or a malfunctioning oil seal, which allows pressure to build up inside the transmission. Additionally, a clogged vent hose can prevent proper airflow, leading to excess pressure and oil being forced out. Another possibility is that the gearbox could be experiencing excessive wear or damage, causing increased pressure and oil leakage. Regular maintenance and checks can help identify and resolve these issues.

There is a vent hose from the engine that runs underneath the truck on top of the transmission on my 2002 Chevy Avalanche can you tell me what this is It has some oil residue in that area?

The vent hose is for either the transfer case breather or the transmission breather. A light amount of oil residue is normal. If there is a lot of fluid coming out of the hose then it is most likely caused from the transmission getting too hot.
