| Does a 54' bug split case have 2 fill and drain plugs? Is the tranny fluid in 2 separate compartments? Thanks for any help. |

| No, just one compartment, it's on the right-hand side though. I'm not sure what the 2 plugs on the left are for. |

| Hmmm, I'm a bit confused. I pulled a drain plug toword the motor. This drained completely. Then I pulled another plug, closer to the nose cone of the tranny. This released more oil. Any more insight? |

Sorry, there is only 1 fill plug, on the right hand side. There are 2 drain plugs but that is only because the tranny fluid gets trapped in the 2 different sections. There is a ridge between the 2 sections.
The 2 sections are connected though and filling it through the 1 fill plug will fill both compartments. |

Refill is the side plug. Make sure to loosen that plug before you drain the gear oil.
Guessing a typo on that 80-09 but 80-90 should work.

Not exactly sure when that changed. There is a Dec 1955 transmission for sale in the classifieds with pics that appears to be the bolt head style you referred to.

The two plugs on the left side are to access the clamp bolts securing the shift forks to the shift rods. Through those holes you can adjust the forks to center in the neutral position.

There's a 17mm or 19mm (think 19mm) on the passenger side, it's a regular hex head plug (not the reversed hex like late models)
You need a fill pump that attaches to the oil bottle and you pump it in...it's a hand pump
It is not an 11mm 1/4" hole... |

Nope not a 19mm nor 17mm, mine is a small hole, less than a 1/4" I crawled all over that trans..researched and this small hole has to be the fill hole...

If you're still reading this... I put Redline MTL in my 1959 split-case and that stuff is like a rebuild in a can! My second gear syncro went from not working up or down, requiring me to double clutch into second everytime, to working flawlessly with the addition of this oil. It didn't happen instantly but took some time to wash the old oil out and make the syncro work.

MTL and MT-90 certainly provide buttery smooth shifting .. possibly the smoothest I've felt. Unfortunately, these oils are not suitable for heavily loaded R&Ps .. they are transmission oils, not transaxle oils. Even the RedLine website now admits this. So, I guess I would use them for a balky trans that I knew I would be replacing some day, but not in a newly rebuilt one that I wanted to last 150K.
