GEAR M UP Posted October 27, 2004 Author Report Share Posted October 27, 2004 Well I just got the bad news...... Trans just took a crap when they were getting the dyno #'s...... I'm starting to look at Rossler and FLP now....... Quote Link to comment Share on other sites More sharing options...

GEAR M UP Posted October 28, 2004 Author Report Share Posted October 28, 2004 (edited) I have not seen the dyno sheet yet...they shut it down @ 4,000 rpm because of the intake/trans issues...... The motor was running out of air and the trans were not reactive at the higher rpm's..... @ 4,000 rpm 380 RWHP and Crank HP was in the 550 range when they shut it down..... For right now, A dyno queen she's not.......... My stock intake and trans are the limiting factor right now, but the stock intake I can work through with a little research........ My issue is the Transmission...... On the road she feels really strong, all 4 break loose and she pulls strong until it shifts. I noticed that the transfer case is making some wicked noise also. I hope to get some track times before the trans blows completely...... I have a price on a 4L80 trans conversion, it has been in a blown 408 for the last few months with no problems, but its up in the $5K range...... FLP 4L65 Stage V is in the $3500 range???? I really want to come up with something to do with the trans and keep this motor in this truck... If I can't, the motor will go into the Vette and I'll do a head/cam combo on the stock motor over the winter. I'm open to all suggestions......

BigTex Posted October 28, 2004 Report Share Posted October 28, 2004 I know no one has a good plan for an AWD 4L80 upgrade yet. I don't think you need a $5K trans or even a $3.5K trans. I'd look into a mildly built 4L80, which aren't too expensive. Speartech sells a harness to control the 80E. The crossmember takes some minor fabrication. Then its on to the transfer case..... How about a manual selection 4wd case from a HD pickup? You can keep it in 2wd for normal driving, then move it to 4WD when you need traction. This should handle more torque than you can give it.

zippy Posted October 28, 2004 Report Share Posted October 28, 2004 i wouldn't recomend the 4L80E if you're planning to get rid of the truck soon. if i recall the reason you wanted the 427 is because you plan to get rid of the truck soon. that's alot of conversion for something on it's way out.

GEAR M UP Posted October 28, 2004 Author Report Share Posted October 28, 2004 I'm pondering the 4L80E, but will that be a reliable solution? How much HP does that trans loose? I've heard its great for low-end torque, but that can’t be super efficient. I love my truck, but my transmission has always been an issue. This will be #3 factory tranny for me. Then again they have all been stock transmissions. I going to give it a try, but I need some more info from guys that are over 400 rwhp/tq. What are they running in there trucks?

zippy Posted October 28, 2004 Report Share Posted October 28, 2004 the stock part is the main issue you're having with that trans..... Quote Link to comment Share on other sites More sharing options...
