braking? during the 2-3 shift

[johnceggleston]

97 gt auto wagon (142k) with 96 2.2L (125k) swap. auto trans was replaced former owner, so the mileage is unknown but i assume it's less than 142k. during the swap, subaru wires, ngk plugs, new t-belt, idlers, wp and seals all around.

 

i've only just started driving this car, so my experience is limited, and i don't know how it drove before the swap.

 

when accelerating from a stop up through the gears there is a braking or drag effect when shifting from 2 - 3. under hard acceleration with no pedal adjustment it can last several seconds, in normal driving it just a short but noticeable lag in speed.

 

i searched and found a thread, on target, but with no resolution.

i'm very reluctant to adjust a trans that was working ok for the PO, besides i don't think they get unadjusted very often. without any real knowledge, i was wondering if the slight power difference between 2.2 and the 2.5 could make a difference. doubtful. i have the TCU from the 2.2 legacy wagon that i could try but again, doubtful.

 

tps sensor??

 

thanks,

john

Loosen the brake band adjuster by just a hair.

 

The adjustment is actually easier to get at than it looks.

 

17mm to loosen the locknut, and a 10mm open end to turn the adjuster.

 

I suggest adjustiong 1/4 turn 1st. Then another 1/4 turn if that isn't enough.

 

 

 

 

If you don't notice a change from that, it probably isn't the problem, and more adjustmnet won't help.

 

If that is the case, it is likely a failing one way clutch, so a set of planetaries is trying to spin in reverse while the sun gear is driven forward. Makes for an odd driving transmission.
