BigWill_21 10-08-2004, 10:34 PM How can the Tech II hold the tranny in gear???? Whats the purpose of doing this??? Can someone please explain this stuff to me!!! I am a learner.. BIGhttp://www.dieselplace.com/forum/smileys/smiley2.gif Diesel Power 10-09-2004, 04:22 AM i would suggest doing a search for tech 2.. a tech2 connects to the OBD port and can command a gear for troubleshooting at the dealer.. we use it to lock it in 4th gear to make a long pull on the dyno. nwpadmax 10-09-2004, 08:08 AM A friend of mine is a GM mechanic and we fooled with a Tech 2 last weekend. It has controls to select a gear and to lock/unlock the TC (and maybe more, we're just learning it too). Now, we could not get it to lock the TC in 1st. However, if we let it shift into 2nd, we could hold it there and lock the TC. I could drop er down to 1000 RPM and it would hold.....mash on the gas and she lugged like a manual. Same thing for 3rd, didn't try other gears. The purpose is for doing diagnostics and singling out where problems may be in the tranny. Or for entertaining two goofballs in a truck on a back country road....http://www.dieselplace.com/forum/smileys/smiley17.gif Burner 10-09-2004, 12:05 PM nwpadmax ...... try this....... get rolling, lock'er into 4th and slow down to about 1200 RPM.....then take her WOT and hang on. http://www.dieselplace.com/forum/smileys/hihi.gif The chugg'n machine will bolt like a whore in chruch.

Won't hurt it. mike Dmax Tim 10-10-2004, 06:22 AM Some people have TOOOOOOOO much time on their hands http://www.dieselplace.com/forum/smileys/hihi.gif nwpadmax 10-10-2004, 02:39 PM nwpadmax If you want to play some more and really want tcc in first, put the Tech 2 in hot mode.

Mebbe next weekend http://www.dieselplace.com/forum/smileys/smiley4.gif Are there any "side effects" to Hot Mode? Does it de-fuel the engine or limit rpms or whatnot to try to save the tranny? Or is it just lock it & rocket? Burner....I'll try 4th lock WOT from idle AFTER the tranny is beefed.....probably slip the hell out of it with comp juice. Got a lot of work to do over the winter..... nwpadmax 10-10-2004, 02:40 PM Tim- Whayre ewe be in O-Hi-O? | ||
