Result! Sort of…

I just replaced my 904 in my 73 Dart, it's coupled to a stock 2bbl 318. Set the kickdown linkage up the factory way. WOT=linkage at full pressure with aprox 1 turn of play between the two.

When I first replaced the transmission the 1-2 shift was so quick and so subtle I thought it was starting in 2nd, the 2-3 shift was very soon to follow, around 25-30mph, also no kickdown.

Also when shifting manually through the gears there was slipping between 2nd and 3rd. After that happend once, I immediatly parked the car to THINK about a solution not drive and test, drive and test to the detrement of the trans possibly.

A quick fluid reading HOT in N resulted in adding aprox 3 quarts! Still 1 pint under but now I"m getting there. A quick/crude adjustment of the kickdown linkage to apply more pressure than it "should" in combo with the fluid and RESULT. Good snappy shifts under half throttle, smooth almost to smooth shifts at low throttle, NO slippage of any kind, and kickdown at between 85% throttle and WOT.

Now maybe I'm being an obsessive dweeb here but, to get the line-pressure such that it operates properly now (still needs fine tuning) I've got it a good 1/2" further forward than it would be using the standard method of adjustment. The kickdown linkage isn't interfering with WOT it just sits further forward than it's "supposed" to.

Is this a problem, can it do my trans harm? My car is a former /6 vehicle, perhaps I still have the /6 linkage in there? Any way to tell?

Last thing I want to do is fry this new/used good trans.

So many ?'s.....TIA
