Feeling pretty stupid ….maybe.

So the car is on the ground, and the engine runs like a mad banshee! Success! (sort of) The transmission started leaking on the first good highway run, and the more I drove it, the worse the shifting to 4th gear got. Replaced the rear seal and …she still drips oil.

But… good news first. The shifter that I fabricated works awesome!

I am still waiting on the shifter ball to arrive, but otherwise I am really happy with the operation. I may go back later and replace the Ford tie rod end with an actual Heim joint.

Now, back to that transmission. I researched this thing to death when I set out to do the conversion. I knew the NV3500 was what I wanted due to availability and the tall 5th gear. I found one on Facebook Marketplace for a few hundred dollars. I got it home and it sat for nearly 8 months without me touching it. In December I set out to install it behind the new motor. I had to fabricate that mount I talked about in the last posting. Everything is married up and off we go down the road.

So this thing… let me tell you about this thing….

Now that I started having issues, I started doing the Google search from hell. Nothing I found married up, not even the rear seal. SO now… here I am feeling like an idiot, how in the hell did I buy and install an AX15 transmission without even realizing it! JHC! Now I started feeling sick. But… as a mechanic I started working on solutions. The opinions on the AX15 are split down the middle with the NV3500. The oil leak … well that is because the slip yoke that came with the trans is worn out completely. Close to .100 smaller than the new one. Ok, so that’s an easy one. I have a yoke for it. The gear clashing… well it appears that the AMSOIL GL5 synchro oil I put it is absolutely the WRONG oil for the trans! So.. fingers crossed that the 4th gear synchros have survived and I’ll have it sorted out with the new Redline MT90 arives from Amazon.

I have a line on an actual NV3500. (Luckily they are paretty much a plug and play swap except for the slip yoke) Otherwise, I’ll just wait and see what happens after the new slip yoke and oil change. I’ll continue to kick myself in the ass for the next few months for missing this in such a HUGE way!



Wish me luck!
