Guest spongebob Posted January 26, 2013 Share Posted January 26, 2013 great, i just lost the allison 6 speed tranny in my duramax chevy.....$4800.00 Link to comment Share on other sites More sharing options...
ptt Posted January 26, 2013 Author Share Posted January 26, 2013 ...I read it wrong? I noticed when I depressed the adjustment tang/button and pushed the cable towards the T-Body that it made the racheting sound. I will do it again in reverse....then depress the gas pedal inside the cockpit. I mustve had a dislectic moment! Thank you..... Link to comment Share on other sites More sharing options...

ptt Posted January 28, 2013 Author Share Posted January 28, 2013 I readjusted the tv cable and it once again made the ratcheting noise so apparently the adjuster works. Now all I have to do is get the Ford 4x4 wheel bearing fixed and out of the way so I can get the convertible out of the garage to test drive it. The transmission seems to shift into gear fine when I place it into drive or reverse. Maybe Ill luck out yet. I will post test drive results. Thanks.

ptt Posted March 10, 2013 Author Share Posted March 10, 2013 Been out of town but back now. I drove the Reatta around the block and tried shifting the trans manually but it stays in low. No hard shift into 2nd. Just stays in low gear. Last resort Ill drop transmission pan and see if anything has collected in the pan. Maybe do a fluid/filter change and add some SEAFOAM TRANSMISSION TREATMENT and see what happens. Its either gonna help or its reman-tranny time...

padgett Posted March 11, 2013 Share Posted March 11, 2013 If it thinks it is at WOT (e.g. vac modulator hose off) it may not shift until about 45-50 mph. Link to comment Share on other sites More sharing options...
ptt Posted March 12, 2013 Author Share Posted March 12, 2013 I dont think I got up to that speed but it was certainly wound out in low! No hint that it was going to shift out of low. I dropped the pan and found nothing out of the normal. The fluid was dark but red and no real burnt smell to it. Vac Modulator is next.... Link to comment Share on other sites More sharing options...
2seater Posted March 12, 2013 Share Posted March 12, 2013 If you disconnect the throttle cable it will shift up as soon as the governor allows. If you disconnect and plug the vacuum to the modulator, it will raise the internal pressure to maximum and shift as firmly as possible. The modulator should have little or no effect on the shift speed on this transaxle. It is different than many other GM transmissions. When the TV cable was disconnected previously, did it seem there was a spring loaded feel to the cable when you pulled it out by hand? It should have a noticeable detent feel after the slack is taken up. In other words, you should be able to feel by hand that it is actually moving something inside the trans.

With adjustment made and everything put back together it has a little slack in the static TV Cable position. I just did a pan drop and filter/fluid change with about a half pint of seafoam transmission treatment added. Gonna take it around the block while going through all the gears manually ande see what happens. Will post the results in a few minutes.....

Ronnie Posted March 12, 2013 Share Posted March 12, 2013 (edited) I don't mean to sound critical of what you are doing but I'm wondering why you used such a small amount of Seafoam Transtune? Isn't a pint the recommended amount? If I were going to use it I would have used enough to make a difference. You can leave it in the transmission after you add it without replacing the fluid again. Seafoam is certainly not going to hurt a transmission that you are on the verge of replacing anyway.

Still stays in low. Added the rest of the pint and went around again to no result. Maybe if I let it sit overnight it may do better but it appears like thats wishful thinking. I did notice that when I tried shifting it manually it would go into a neutral like state when I moved the shifter out of 1st into 2nd, drive or OD. When I moved the shifter back to low gear it would shift down to 1st. Just wont move in any shift position but 1st (low). Im going to try another test drive today and see if anything happens. Not optomistic. Local Certified Transmission shop gets around 1400 for remanjasper wants 1800 and 400 core refundable when they get your core in specific shipping configuration.

padgett Posted March 13, 2013 Share Posted March 13, 2013 Can use diagnostics to see what gear is being requested when in drive. I'd put in diagnistic mode, get up to 30-35, shift to D and see what gear the HVAC says is selected. After that, the next step is either a line pressure guage or a different/rebuilt trans.
