ATSG stands for Automatic Transmission Service Group, they produce manuals for most common, and uncommon trannys. See URL: http://www.txchange.com/atsg.htm Our tranny is listed as Subaru 4speed. The manual is cheap, comprehensive, and in fact this should be listed as one of the LINKS on our main site resource page. You could do worse than buy one, from memory mine only cost about $17 or so. Regards lockup during acceleration, I will switch on POWER mode and check for you. I do believe it will only work for gentle acceleration. If you ask for a heavy load, then the torque converter has to be brought in to multiply up and do the work. I ran mine for quite some time in POWER mode. It was harder on fuel, 2-4 mpg. However, you might expect this as a trade off. What you got in return was willingness to change down quicker, and also holding on to lower gears longer. With the extra revs used, you had to expect heavier consumption. It was, however, much more fun. It is my pet theory that this higher consumption was the reason Fuji discontinued the POWER switch on JDM cars about '94. Joe

Greasy fingernail test
John
I forgot to mention. I gave the tranny shop all my info on trannys, the SM volume, the ATSG, the End Wrench overview, and pages from DRW, Level 10. When I got them back, the ATSG was the one he apologised about the greasy fingerprints on. That should tell you something!! Joe

I have also noticed that I will get a quicker 2-3 shift in power mode at WOT than I do if I am backed off the throttle slightly. I mean that the shift itself will occur faster - not that the car goes faster. However, with the throttle backed off slightly the TC will slip during the gear change and with the increased rpm the car will feel as if it accelerates faster - it will 'jump' forward more powerfully as the shift completes. This happens in both svx's I wish I had a light that lit up when the TC was locked so I could figure this out.

<< (1) Normal control:- Control content; *Lock-up on/off characteristics are set for each range, gear position and pattern by throttle opening and vehicle speed. *Fuel consumption, power performance and shift characteristics are taken into account. (2) Smooth control:- Control content; When switching from lock-up off to lock-up, the duty ratio{of the control duty solenoid} is first set to 25% and gradually changed to 95% for smooth lock-up operation.>> If the solenoid is at 5%, the lock-up is off, and if at 95%, it is totally on. Another paragraph about the Smooth operation explains further:- << DURING SMOOTH CONTROL When the lock-up clutch is operated, the duty ratio of the lock-up control duty solenoid does not increase directly to 95%. Instead, it is first modulated to a pre-set value then smoothly changed to 95%. This operation allows lock-up duty pressure to be changed smoothly, achieving shockless engagement of the lock-up clutch.>> Hope this sheds some light on it Joe

This topic is really getting interesting, although a little over my head as I have only a very vague understanding of auto boxes and even less of torque converters. Is there anyone who can look into this deeper to give a definitive answer? It may also be useful if this info was collated somewhere for future reference.

Power mode to converter lock-up.
I can't see the torque converter locking up at any other time than when the car is cruising in Drive with warm oil.
When power mode is engaged, accelerating is the main objective. In this case the torque converter plays an important part in gearing down and increasing of torque to achieve the fastest acceleration. The TC lock-up would be designed to be operating, to allow this car to cruse at high speed economically, to remove that last 5% slip when the converter is not needed. Yes I think the book is confusing, in the way it is suppose to work. I am sure that my 95 mod only locks-up under the above conditions. Harvey.
