MaroonRegal Posted October 10, 2003 Report Share Posted October 10, 2003 quote: Originally posted by RedRegal96 How is it that you can put that much power through a 4t60E without destroying it? --Scott Dunno, it has about 30,000 miles on a stock rebuild in which the only mods were shimming up the shift accumulators and adjusting the modulator a little firmer. There are more than a few people running 12's and 11's on the 4T60-E without any major issues. I know one guy has really not had any issues other than breaking CV axles, he is running mid 11's in a 3800IISC Fiero w/ 4T60-E. I am running a 50/50 special mix of trans fluid tho. 50% Valvoline Durablend DexronIII/MerconV; and 50% CAT 30w trans hydraulic oil. Shifts really nice and when I pulled the pan 2 weeks ago it was so clean you could eat off it. This is from a thread on gmtp.net It's in reference to a Fiero running a turbocharged 3800 Series II.

godofthunder Posted October 10, 2003 Report Share Posted October 10, 2003 when at the Super Chevy show...there were tons of Impalla SS (the ones on the caprice frame in the mid 90s). They actually use the 4L60E, the same trans as mine, only longitudinal, rather than ours that are transverse. And those things, if im not mistaken, are up arround 300HP or something? I wasnt to ask the user if he ever had tranny probs jon Quote Link to comment Share on other sites More sharing options...

I wasnt to ask the user if he ever had tranny probs jon That's because there is less stress put on the axles/transmission/etc. when it's run in a RWD configuration. 8) All it has to do is put the power from the motor to the driveshaft. It doesn't have to worry about the half-shafts turning or flexing etc. Plus the transfer of power is smoother. Problem is you lose a good deal of power with that driveshaft.

MaroonRegal Posted October 12, 2003 Author Report Share Posted October 12, 2003 Yeah, but you need more than 300hp if you want a really fast RWD car. Whereas 300hp in a FWDer is a freaking shitload. Quote Link to comment Share on other sites More sharing options...

Not EVEN the same trans except for the 4 and the 60E in the designation. The 4L60E is the electronic version of the 700R4 and shares NOTHING with the 4T60E. The actual transmision case and all minus the bellhousing and differential from a 4T60E would practically fit inside a 4L60E case. I wish they were the same.

MaroonRegal Posted October 12, 2003 Author Report Share Posted October 12, 2003 I was just thinking about that Turbo'd Fiero, and I wondered if the fact that they have that 4T60E on the rear axle would make a difference. There'd be less shit going on with that axle, obviously. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted October 12, 2003 Report Share Posted October 12, 2003 A guy on one of the forums (Zoomer) has a 97 GTP that is running high 11s with 4T60E.. i don't know if anything was done to the tranny or what. I thought zoomer has the 4T65E-HD????? Tom Wright was running mid 12's in his L67(whipplecharged though) first gen Lumina w/ the 4T60E IIRC, I believe he was/is breaking trannies left and right though.

dbtk2 Posted October 13, 2003 Report Share Posted October 13, 2003 A guy on one of the forums (Zoomer) has a 97 GTP that is running high 11s with 4T60E.. i don't know if anything was done to the tranny or what. Ummm....Zooomer has an INTENSE 4T65E-HD Tranny and runs LOW 11's...as well as the INTENSE Turbo GTP that runs mid 10's. Those trannies aren't stock AT ALL. 97+ GTP's have 4T65E-HD trannies. GTP's running 12's or faster normally tear up trannies left and right, even with the 4T65E-HD...the 4T60e would be a joke. Not that the 4T60e isn't a good tranny, because it is, it just doesn't do too good with twice the power it was meant for. Quote Link to comment Share on other sites More sharing options...
sonyman87 Posted October 13, 2003 Report Share Posted October 13, 2003 I totaly agree with dbtk2 the 4t60e can barely handle the hp of a high modded 3.4dohc how would you get a 4t60e on a l67 anyway.. if thats possible why couldnt i bolt up a 4t65e-HD up to my 3.4 dohc? have a transmission that could handle 250hp without shitting a brick.

MaroonRegal Posted October 13, 2003 Author Report Share Posted October 13, 2003 Well, my 3800 Series II (L36) is bolted straight up to a 4T60E, so I don't see why we couldn't just drop in a 4T65E-HD...unless there are other circumstances like axle compatability.

Stock...maybe 400hp, not sure for how long though. The INTENSE transaxle can hold over 600. 8) Quote Link to comment Share on other sites More sharing options...
RomeoZ34 Posted October 14, 2003 Report Share Posted October 14, 2003 The stock one can't necessarily hold for 400, and the INTENSE can't necessarily hold for 600. I have heard guys breaking stocks ones with just a 3.4 sc pulley, and people going through INTENSE trannys w/ less than 600. Tom Wright's whipple charged L67 had a 4T60e, that he had done extensive work on through aP (animul performance, his own company), I believe it involved more clutches or something. And big whoop, a Fiero has a turbo 3.4 on a 4T60e. Think about it, how much do you think a Fiero weighs? Compare that to a W-body and there is the mystery there. The only way to use the 4T60e on a W-body w/ out blowing it up is to go to ASG, and even then it is essentially a STRENGTHEND caddy transmission in a 4T60e housing.

You have to remember that not every single part is created equal. Yes, people have blown them with less hp and less miles. My numbers were on AVERAGE. I guess I should have stated that.

dykz34 Posted October 14, 2003 Report Share Posted October 14, 2003 Tom Wright is NOT running a 60E. He is running a 65E. The reason he blows up so many trannies is probably because he doesnt know what the fuck he is doing when he rebuilds them. The 60E is rated at the SAME HP and TQ as the 65E.

Strangely enough..I've had a lot of people tell me that And they don't put the L67 on top of the 4T65E...they use the 4T65E-HD for the L67. Supposedly all that's different between the two is the differential...but I'm not sure about that one. :? Quote Link to comment Share on other sites More sharing options...
dykz34 Posted October 14, 2003 Report Share Posted October 14, 2003 I dont know much about the 65E's, but the difference between the 60E-HD and non HD is not the differential. There are more clutches in the HD. Again, I dont know how the 65E is setup. Quote Link to comment Share on other sites More sharing options...

dykz34 Posted October 14, 2003 Report Share Posted October 14, 2003 Just because a tranny is HD doesnt mean its immortal. They can blow up just the same. How many ppl. bought these cars to mod them? VERY, VERY few. Thats why the HD wasnt a big problem in GM's eyes..... a Lumina/Regal/Cutlass/Grand Prix isnt a Corvette. Quote Link to comment Share on other sites More sharing options...

1badtgp Posted October 14, 2003 Report Share Posted October 14, 2003 So since we are on this topic, obviously the 4t60e is stronger than the 440-t4 right? Is there a hope I can squeeze one in my TGP with the 3.1? I'm tired of replacing trannies, and hopefully that can hold up to more than the 440's.
