Thanks for the reply. The viewport is either plastic or glass, do they break easily? What tool should I use?It's an easy job on that model!
Jack up the front end to send all the fluid to the back if the transmission, then unscrew the sight glass and install the new one.
Thanks. I will give it a shoot.They are plastic, they do get brittle in time.
To remove a pair of pliers, Install hand tight.
Thanks for the advice guys. Once I learn there was a pin to keep the clutch engaged, I was able to remove the old viewport by hand. Didn't see anything wrong with it but replaced it anyway. I used the front end loader to lift the front end and had no leaking at all while I was changing the part. Letting it sit right now to see if the problem is corrected. You guys are most helpful and I appreciate your advice.Had to replace the one on my L3400 last year. Wolfman is right, they get brittle. The threaded plastic around the sight glass had cracked, and actually fell into pieces as I was taking it out. New one seems to be made out of tougher material, felt more solid. Be really careful as you are removing the old one that pieces don't fall into the tranny.
