jack45 Report post Posted February 27, 2012 I have 3000 6-speed on my 2004 Allegro and was told that you could reset/reprogram the transmission by removing and replacing (after 30 seconds or so) the fuse to the transmission located at the chassis batteries. Anyone heard of this? If true, what’s the procedure (engine running/off)? Thanks Share this post Link to post Share on other sites
wolfe10 Report post Posted February 27, 2012 First, this would ONLY be done with the engine off. Most transmissions have TWO fuses-- a smaller one for memory and a larger one for powering the ECM when running. And all this will do is reset the "adaptive" aspects of the transmission shifting. Though it takes longer, just driving will "adapt" the transmission to your driving style. What are you wanting to change? Share this post Link to post Share on other sites
jack45 Report post Posted February 28, 2012 I recently returned from out west traveling some pretty good grades and since returning noticed the shifting not to be as smooth as normal. I was discussing that issue with someone promoting changing to Amsoil synthetic and also mentioned the fuse thing to help out. Share this post Link to post Share on other sites

Have you had your transmission serviced? Is it time for service? Share this post Link to post Share on other sites
jack45 Report post Posted February 28, 2012 Have 70,000 miles on coach. Changed transmission fluid & filters around 45,000 miles Changed the transmission filters around 60,000 miles Share this post Link to post Share on other sites
wolfe10 Report post Posted February 28, 2012 Are you using Transynd. You don't give us any chassis or coach information, but many came from the factory with Transynd. I would stick with it. Change intervals are a lot shorter if using a regular Dexron product. And I doubt that Amsoil is any less expensive than Allison's own Transynd. Share this post Link to post Share on other sites

wolfe10 Report post Posted May 4, 2012 AMSOIL says their, "Torque Drive" synthetic AT fluid meets ALLISON TES-295 SPECIFICATIONS If it is on Allison's "approved fluids" list AND is less expensive, then you might consider using it. If it does not meet both criteria, I would NOT. Said another way, there are enough "Allison approved fluids" that I would not risk a non-approved one.
