I'll keep this as simple as I can
1997 Ford F250 PSD
The shift from 1st to 2nd is shockingly hard when I keep consistent throttle (around 2000 RPM it shifts norm driving conditions) but if I let off the throttle, to drop the RPMs, it shifts so smooth you can hardly feel it. If I really get on the throttle and get some speed it'll shift a little bit better but its as if I have to hot rod the thing to do that. It doesn't matter how slow I go ( almost worse if trucks forward movement is slower when shifting at the higher rpm) It'll always slam in. The rest of the gear shifts aren't really that bad. Downshifts are smooth as butter.
-Rebuilt transmission from Chippys out of West Virginia with about 2000K miles on it.
- They put a transgo shift kit in it
- Not sure what they drilled the holes in the shift plate to ( could this be the whole issue?)
-The first shift of the day from 1st to 2nd is actually pretty smooth but every shift from 1st to 2nd after that is rough and rumble
-I have no check engine light on or codes that I can read from the OBD2 scanner ( Torque app )
-Overdrive works as it should
-No noticeable needle fluctuations (speedo or rpm) while driving or during hard shifting
-No issues with idle or stalling or unexpected gear shifting etc
The truck runs magnificently other than that ( and a bit of a howling around 1500-2000 rpms which i think is the down pipe rubbing the firewall) but its enough to annoy the living hell out of me. I just want it to drive easy and smooth ya know like a normal truck should.
Seems to me like the timing of the shifting might be off or I'm not making enough speed for that first shift which then would be a total diff issue. Could use some guidance
