My built 80e seems to still shift too hard. Actually seems really random at times with its shift firmness. I keep reducin the base pressure on the shift. THe force motor table is stock also. Im sure it has a valve body kit in it as well. Is there any thing else I can do to lower the pressures. Ive gotten a bit worried there too low, I assume a good shift means that I shouldnt worry too mucha about the values though.. The shift is still firm though. THoughts?

Heres a tune, DO not take it as a whole. But it does have my trans segment.

 

**nevermind**

 

What about adding a lil torque management? that should help some even tho its Vac Moded.

 

Thats why its so hard!? lol I had a EPC put into it. electronic pressure control.

That vac regulator had problems to say the least. I had tranny oil all the way into the intake from that vac line also.....


ANyone else? I thought of TM, but I dont like the idea of cutting the powere down to shift.

 

Ah ok I forgot that you ditched the vac mod, my bad

 

ha, thats what i did on mine.. had to keep the 1-2 from spinning the drag radials at the track so i put 10% TM in.. it did the trick. i mean come on, you have a 80E now.

 

90mph chirps cant be good for anything. guess I will keep lowering it a bit. look at the very end of that log. Watch mph.

 

i wouldnt lower the pressure too much..

 

Well I feel I will bo ok but that what Im asking. Its still a firm shift, I guess from the drilled valve body? But as long as its a good shift am I ok?

 

My Force Motor Current table {D3801} is identical to yours and stock AFAIK.
My Base Pressure 1 -> 2 Shift {D0701} is quite a bit lower than yours. I lowered my Normal column by 6 from 160 NM to the bottom of the column. I have been running these for over a year and my 1 -> 2 is still firm at times.
