A727 Rebuild kits redux - Rebuild kits everywhere (62-70 vs 71+)
Very Intresting Thread, I am just starting my First with Full Reverse Manual Valve body , Did you get it all finished and driving ?????? how did it all go
so whats the verdict AIV , does it run and shift as great as this thread is ? lol
I know it has been a very long time since this thread was active but I wanted to circle back with some results.
I've been driving the car for about a month now and I'm pretty happy with the transmission.
The transmission does everything I needed it to do but I have been working out some issues and fine tuning.
Keep in mind I am running 3:91 gears in the back with 26" tires and a B&M 2400 stall converter
For starters, I have Park, R, N, 1, 2 and 3(D) using manual shifts. I can shift up and down manually through the gears.
It will shift up and down through the gears if I leave it in Drive.
The shifts are tight and firm.
Some initial results
Auto:
- If I ease onto the throttle I get a 1-2 shift at 5-7 mph and a 2-3 shift at 12-15mph.
- If I get on it, The shifts happen very quickly and are very close together practically on top of each other.
- If I stomp down on the throttle at 40 mph I don't get a kick down.
Manual:
- If I start in 1 and ease on the throttle the car will shift to 2 and stay there until I shift to 3. The 2-3 shift is firm unless I shifts early then it slams.
- If I start in 1 and get on her it will hold a little longer in 1st allowing me to shift into 2 and it's firm.
- I can feel the transmission shift up and down manually through the gears
I adjusted the KD linkage per the manual this is the latest 1-2, 2-3 results after the test drive.
- Low load easing out shifts were 5 mph and 10 mph
- Moderate load shifts were 8 mph and 15 mph
- Hard acceleration shift were 20 mph and 30 mph
After speaking with Tom Hand (Thanks Tom!) I've come to the conclusion the the B&M 2400 stall converter is too tight for my application and worked with Chris at Continental converters to make a custom converter which I have yet to install.
I am still trying to diagnose why I can't get it to kick down from 3-2, my next step is to pick up a gauge and check the pressure.
Until then I just row the shifter by hand. It's quite fun!
