I had my 2004r rebuilt about 2 months ago and very shortly after i noticed the first time after the car sat for awhile and cooled down the 1-2 shift would hold and then finally slam into second, its been doing this ever since also i would have to let off the gas to get it to go into OD and now today i drove the car( i just installed new cam and intake) and now the 2-3 is hold as well and have to let of the gas to get it to shift. I checked the fluid and reset the TV cable and still the same. I have one of bruces D5 conveters, trans go shift kit and a tranny cooler. Anyone know what might be causing this.
