Default Torque Management?

I just had my Py3600e installed last week and I'm not sure what it is but if I am 1/4 throttle to 3/4 throttle when the 1-2 shift happens the car stumbles a little, not a shutter but just like the car was reacting late when going into gear so it's like you start going and then the shift happens (pause) ... start going again. It does not do this WOT or if I am barely accelerating.

Place that installed it told me it's just the stock tuning not knowing what to do with the different converter.

Converters tend to make the shift feel sloppier and some people report they notice the torque management more with a converter.

Double check your fluid level when hot.

If fluid is ok what else could it be? Fluid still looked very clean I might add, I used a brand new white cotton towel to wipe it on.

Is this Torque Management? Should I worry about this? Today when I started me car let it idle about 25 seconds, waited stoped to merge on to a road for about a minute and a half, I proceeded to go got on it about half throttle, 1-2 it really slipped, 2-3 very mildly. Never slipped that bad on 1-2 yet so kinda caught me off guard.

Running Valvoline Max Life ATF if that makes a difference.

It's just the slow, sloppy shifts of a stock 4L60E. Torque mgt. makes the car annoying to drive; mine would literally nose dive with normal driving on the shifts! The TransGo shift kit did help a lot at part-throttle and made it great to drive again. However, at WOT the tq. mgt. got worse. You could actually see the car nose dive on both shifts. The only way to cure tq. mgt. is to have it deleted from the PCM. You'll have a grin on your face for weeks after it's gone. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Default Re: Torque Management?

Torque management is a function of the PCM that reduces engine power
under certain conditions. Torque Management is performed for the
following reasons:
To prevent overstressing the powertrain components.
To prevent damage to the vehicle during certain abusive maneuvers.
To reduce engine speed when the IAC is out of the normal operating
range.

The PCM monitors the following sensors and engine parameters to
calculate engine output torque:
Air/Fuel ratio
Mass Air Flow
Manifold Asolute Pressure
Intake Air Temperature
Spark Advance
Engine Speed
Engine Coolant Temperature
A/C Clutch Status

The PCM monitors the torque converter status, the transmission gear
ratio, and the engine speed in order to determine if torque reduction
is required. The PCM retards the spark as appropriate to reduce
engine torque if torque reduction is required. The PCM also shuts
off the fuel to certain injectors to reduce the engine power in the
case of an abusive manuever.

The following are instances when engine power reduction is likely to
be experienced:
During transmission upshifts and downshifts.
Heavy acceleration from a standing start.
The IAC is out of the normal operating range.
When the driver is performing harsh or abusive manuevers such as
shifting into gear at high throttle angles or shifting the
transmission from reverse to drive to create a rocking motion.

The driver is unlikely to notice the torque management actions in the
first two instances. The engine power output will be moderate at
full throttle in the other two cases.

The PCM calculates the amount of spark retard necessary to reduce
engine power by the desired amount. The PCM disables the fuel
injectors for cylinders 1, 4, 6, and 7 in the case of an abusive
manuever.

Do an idle relearn procedure on it and put 50-100 miles on it and the car will recover. At least it did for me. You will still get the TM nose dive when you exceed the torque/HP limits , but it will feel much better than what you are experiencing. I was about to pull my ST3500 out , but it feels real good now. For some reason out of the blue (NMB) , I have to do an idle relearn, but it gets me back where I want to be. Try it and let us know. Good luck!!!

I thought I was having super bad TM, getting one hell of a nose dive on the 1-2 shift. It took me quite a few logs to see I was hitting the rev limit on the 1-2 shift. For some reason Autotap would not pick it up. I finally had to monitor just current gear and rpm for several runs until it showed it bumping the limiter. Setting the rev limit up slightly helped me. FWIW.
