Hey!
I rebuilt a transmission --with the help of a professional-- for my 1990 colony park wagon.
It's an AOD with several internals from an AODE for the 2" OD band, and mechanical diode reverse drum (what the OD band rides on), A++ OD servo, and a slightly higher rpm torque converter.
It also turns out it's the longer tailshaft version (oops). Guess it didn't come from a mustang like the guy told me.
Anywho.
Installed it tonight, with a properly fitting driveshaft, and took it for a spin.
The shifts are at higher rpms, but, that's what I wanted. Maybe 2000rpm for 1-2 and 2-3.
If you feather it, it shifts nicely. Upshifts are a bit delayed versus what it used to be.
So far so good.
However, if you add a bit of gas, it wants to downshift quite prematurely. Seriously; if you are not feathering the gas pedal, any bit more pressure, it tries to downshift.
And when it does try to, it fails. The engine revs to 3 grand while the car feels like it must be in neutral.
So something's up with the kickdown cable.
Of course, I messed with everything around the transmission. If you can adjust the kickdown cable at the transmission, then, it's possible I didn't resecure it in the same place. Or maybe the amount of tension that worked for my old AOD doesn't work for this one, with the higher stall converter, and, possibly, the higher rev regulator-- though I'm not certain of that.
But it bothers me that not only does it try to downshift very easily, but it doesn't succeed in downshifting anyway.
Thoughts on what might need adjusting and how?
That's my hope, anyway.
My fear is that there's something internal I screwed up.
But I was getting these shift flares both in 2-3 and 3-4, corresponding with trying to accelerate a little harder. It doesn't feel like it's just one gear that's not holding, but, specifically when I give it more gas and it feels like it's trying to downshift.
