thomp62301 Posted January 21, 2006 Report Share Posted January 21, 2006 Need help everybody, I'm pretty dumb when it comes to these electronic transmissions. I have a 150 NX wet shot on the truck and it's great. Expecially when your killing Lightings. But i'm starting to feel alittle bit of slipping in the transmission. I wanna be able to launch this thing on nitrous and not worry about the trans. Anyway, if your runing a running big power adder, what did you do to the transmission, and what do you think you spent on it. Thanks for any help.

detjoe Posted January 23, 2006 Report Share Posted January 23, 2006 I wanna be able to launch this thing on nitrous and not worry about the trans. <{POST_SNAPBACK}> then buy a spare, cause this 5000lb truck eats transmissions w/slipping you will need a rebuild, hard part inside, shift kit, servo's... do a little searching and you will find many results.

BenKey Posted January 29, 2006 Report Share Posted January 29, 2006 Have you been tuned for the 150 shot? I wouldn't slap that much on without backing timing down a few degrees. Otherwise, the tranny may not be your only worries in the future. As far as a built tranny, you can go two ways. One, you can buy one built and ready to install. The other way is buy all the pieces and then have them installed. The second is usually a little cheaper way to go. Make sure it has a shift kit already installed and add a beefy tranny cooler.

zippy Posted January 30, 2006 Report Share Posted January 30, 2006 something important to keep in mind with a wet shot. if the air doesn't go through the the mass airflow sensor, the computer doesn't turn up the line pressure to go in line with the extra power output of the engine.

thomp62301 Posted January 31, 2006 Author Report Share Posted January 31, 2006 thanks for all the info guys, i have parts on the way. as far as the 150 shot, the local speed shop said that a computer controled engine such as the ss, the knock sensor would back the timing out if needed. is that true are is that just bs?

zippy Posted January 31, 2006 Report Share Posted January 31, 2006 that is true, but usually before that happens the head gasket will release excessive pressure. Link to comment Share on other sites More sharing options...

thomp62301 Posted January 31, 2006 Author Report Share Posted January 31, 2006 There isn't much for speed shops in my area. Thanks everyone, I have some changes to make. I believe i'm gonna drop the jetting down alittle untill I get the computer programed. Link to comment Share on other sites More sharing options...
Pro Built Automatics Posted February 25, 2006 Report Share Posted February 25, 2006 If you are going to add "nitrous" to this, I would use a setup that uses the "window" switch. This turns off the nitrous during the shifts when setup correctly, which will greatly increase transmission life. Adding a "modified" Trans-Go Performance Shift kit will help out a lot here. The Corvette style servo works fine with this kit, and the oversize 4th gear servo is unnecessary in the vast majority of cases. Remember that working with the accumulators will do a lot towards having smooth part throttle shifts, and firm WOT shifts. Adding a Trans-Go vacuum modulator will also help solve band/clutch problems (improve their life) and will give instant downshifts, not the delayed downshift that the computer provides. The computer still controls the timing of the shifts, just that the vacuum modulator uses "real world" load conditions to determine line pressure (with no delay) as compared to the computers anticipated situation. I hope this helps out some. Link to comment Share on other sites More sharing options...
