Transmission 3rd to 2nd shift shock??

Dragging this up because it matched the issue with 99 Outback. The delay after descending a hill is long enough to warrant a manual shift change. No shift shock happens there. But upon an ascent up a hill, as soon as it downshifts-BAM! Shifting is smooth in other gears and is smooth if it's done manually. Seems like a throttle sensor.

At some point the trans lessened its tendency to slam into 3, so i never figured out what it was (disconnecting the battery and wiping the learning helped for awhile), and at just under 200k the front pinion bearing was making enough noise I just decided to swap in a boneyard trans.

 

Unfortuneatly, 2004 was erroneously listed as a swap into a 2003, and I have to jerry-rig the AWD because the signal to the Duty c solenoid is opposite on the '04.

The filter seems to have made a little difference - not much.

 

I'm going to go ahead and order mounts on payday.

 

Hope you weren't offended nipper. I don't intend to put down anyone's suggestions. Sometimes just chatting with people - even if it's rehashing old territory or seems unrelated - sparks a thought.

 

And you might be right about the mounts. I'll let you know when they arrive.

 

Thanks all

Hi.  I'm haveing this same issue.  Did you ever figure out a solution?

FWIW the ATSG Techtran manual lists the following possibilities:

 

On car check:

Faulty control unit

Valve sticking

Faulty throttle sensor

Deterioration of ATF

 

With transmission out of car:

Overrunning clutch slippage

Band & Servo slippage

Hm it reminded me of the this text:

 

 

f engine speed increases abruptly on 2-3 shift, or if there is a delay of more than 1 second on a 3-2 kickdown, excessive clearance between reverse clutch drum and band may exist, adjusting screw should be rotated clockwise. If there is a braking action on 2-3 shift, excessive small brake band clearance may exist and adjusting screw should be rotated counterclockwise. Adjust brake band as follows:

  1. Using socket tool No. 398603610, to hold adjusting screw in place, loosen locknut.
  2. Loosen or tighten adjusting screw within 3/4 turn , to properly adjust band, then tighten torque to 19-21 ft. lbs.

If slipping occurs on a 2-3 shift, excessive small brake band clearance may exist. If transmission shifts directly from 1st to 3rd, excessive large brake band clearance may exist. Adjust brake band as follows.

  1. Using socket 398603610, to hold adjusting screw in place, loosen locknut.
  2. Torque adjusting screw to6.5 ft. lbs. , then back off adjusting screw 2 turns . Torque locknut to 19-21 ft. lbs .
