Last night, I was tinkering with the shifter. Since the rebuild, the trans has been awesome during all upshifts, but has been hesitant/difficult to downshift into 4th from 5th.
I got it a little better, but still have to really perfectly nail the rev-match to downshift. I'm not sure what's up with that. Maybe it'll sort itself out a little bit as the synchros wear in. IDK.
The new gear oil is much better than the Redline that I had in there before. So that's a relief.
Just need to figure out the shifter adjustment to dial in 4th (without losing 1st or 2nd). I am considering a WEVO Gateshift once I repay this trans rebuild as I've read they can be installed with the trans in the car.
During one of the test-drives, the car was running a bit wonky. So when I got back home, I pulled off the rain hats and set the synchrometer on each TB to see how balanaced/unbalanced they were.
Oi. They were a mess. Now I'm wondering if I'd done a really poor job sync'ing them the first time, or if the adjustment screws have jiggled & jittered their way into new positions. So I'll have to check again in a couple hundred miles. I may have to use a little green loctite if they've moved.
The two things that came of the re-sync are:
1. improved drivability and smoothness
2. I'm getting much more travel of the butterflies. So apparently, I wasn't even close to WOT at what I thought was WOT. Now I need to enlist the help of a buddy or camera to verify WOT at the ITBs when I'm at WOT at the pedal. Nothing quite like finding another 20hp for free.
As usual, I'm still tinkering with the calibration as well. Specifically, I'm working out what parameters to track whilst logging to help me dial it in.
I'm also preparing my winter plans. I have to have a plan, or I don't get anything done.
Stay tuned, this build isn't done yet.
