1991 FLHTC Electra Glide Classic with the 1340 EVO is leaking from the tranny vent tube. This is the 1st I have noticed it. Would running hot cause this? I last tuned the carb the other day and had it idling for a while and throttling the carb a lot to set the accelerator pump. I noticed when i got done there was steam coming from the crank case breather and looked at the temp gauge and it said 250 degrees. So I shut her down to cool and walked away. 2 days later now and I drove it to work. On the way out of the garage I noticed the puddle that was under the motor on floor. Seemed at 1st to me coming from the primary cover but after cleaning it all up i noticed the U shaped vent tube was indeed wet at the end. I recently had a full service done as well changing all the fluids.

What fluid level should I check to make sure I have enough in there? I will continue to monitor from here and hope it was just blow by from overheating. Hope I didn't blow a seal. Thoughts?

 

Check the transmission fluid level.

 

Check the level of the transmission lube according to your owners manual.

The factory has changed the method over the years, some are checked on the jiffy stand, some are checked upright.

They are not all the same.

 

I put redline Trans fluid in my bike yesterday and it is leaking really bad out of the vent hose..... what is the problem? How do I fix it and should I continue to ride it with it doing this?

 

See above answers, you want 23oz.

 

Yeah I put the whole quart in like the guys at the HD shop told me to do and should I check it standing up straight or on the kickstand?

 

Definitely 24 oz max....standing straight up......

 

A quart is 32oz you only need 23oz.

 

Don't listen to those guys....
