You guys need to cut her some slack. She paid the shop money to rebuild her transmission, and it wasn't done right obviously. No matter what the price she paid, it wasn't done correctly. I'll tell you this, there are not too many local shops anywhere that know what they are doing when it comes to these trannys. I see this happen all the time, even if she was putting down 400rwhp it should have lasted alot longer. The point is the tranny shop does not know how to build it properly. With a good tranny cooler, you should have had no problems. I've been through this too, different tranny though, paid for a rebuild...actually two and the shop never got it right. It was frustrating as hell, come to find out this guy was a joker and was screwing people left and right. I had a friend that had his ls1 trans rebuilt extremely cheap because he had the hook up, the only hard parts he bought were under $300(clutches,etc...) He was putting down 390rwhp and beat the **** out of it for over 1000 passes and it never skipped a beat. The first time he had it rebuilt it never worked right, so he took it to a friend of his and he said the previous tranny builder had no idea what he was doing it looked like. It just goes to show that you don't have to put big bucks into it if built properly and not running big hp.

 

After all the good press that Dave@Rock On transmissions gets on here I went ahead and bought a stage 4 4L60E just yesterday. I can't wait to get it. Vacuum modulated to get the computer outta the mix as well.

Hope its lasts longer than my stocker 4L60E, which I call the factory freak. I have over 250 passes on this tranny alone under 3 different FI set ups and 3 different torque converters and its handled all that just fine. I have over 70k miles on the tranny and its barely starting to take a dive....so this ROCK ON Stage 4 better last as long as my "factory freak" as I hate to take these suckers out

I'll treat it no different as well, regular fluid and filter changes and whatever else dave rec's as maintenance.

Dave is it done yet

I had similar issues with my 700R4/4L60. After rebuilding it 3 times, I said F-it! I will live without OD for a bullet-proof trans (Rossler TH400 full race-prep auto valvebody). I have no regrets at all...

 

forget no O/D....get a 4l80e if you make big power and want to keep yours a daily driver type

 

the only reason I did away with OD was $1800 for the TH400 or >$4000 (for myself - no electronic trans controller - modded x-member).

 

Sound so familar, I burnt up 5(warranty) trans in 6 months and combined put 2k miles on them. what a joke, this was Brandon Transmission in Brandon fl. fianlly got another builder. He took it apart and sound ALL stock parts including the Tq converter when i asked for a TCI, he just simply changed the stock stall. We found out several other trannys were done the same way later. Straight up crooks! so fin a reputable tranny shop and pay the difference. Transmission Physcians in tampa fl rules!

 

I say **** the overdrive... a car that gets about 1500 street miles a year and sees 20 to 30 passes.. has no need for overdrive. The world lived without it for years with no issues. I guarintee 99.99% of all the old musclecars you see have no overdrive, and they drive them to car shows and whatnot all the time... no issues. If cars in the 60's came with no OD, then today's technology can live without it too.. that's what I say.

 

When the closest 1/4 mile track is 3 hrs from you and your car is a daily it's kinda nice to have OD

 

if you are only running 11s-12s, you have no reason not to have the luxury of o/d. Lots of old school rods are putting in o/d transmissions so they can drive them further and faster without overheating etc.

 

OD is a beautiful thing, **** why have AC or radios or any other technolgy right? I'll take OD anyday. If I ever build the car to be single digit i'd give up od.

 

My radio, ac, power steering and every other uneeded thign I can find is leaving the car this year.. so I guess I'm in another world I guess...

 

Sure, if your car is primarily for race or show, fine. I've got both and have driven my old musclecars to shows 8-9 hrs. away at 65mph at 3500rpm @ 15 mpg and it's a PITA ... no way I'd want to go back to that on a daily basis after experiencing 80mph at 2500rpm @ 23mpg and all the creature comforts of a modern LS1 performance car ...

 

^^^^^ I agree

 

I agree as well.. which is why I don't rive mine everyday. I guess the point I was trying to make is this... if you want to race a car and not have **** break, put race worthy parts in ( LIKE A TH400 ) but if you don't want to put parts in like that, then don't race the car, because you ARE going to break stuff... pretty much the way it is I think.

I'm not trying to flame or start a war, I just hate hearing people complain when their transmission that was barely adequate from the factory gets an extra 100+ hp thrown at it and then they wonder why it won't stay together. The tranny was meant to handle 300 rwhp max.. show it any more then that, and you are going to cause it to wear out faster, I don't care if it's put together by christ himself, the the tranny was not designed to handle the abuse of racing. Sure better parts can be used, but when it's a flaw by design, there's only so much better parts can do.

 

I guess some people can put up with ALOT more than others.
My one and only daily driver has a th350, non lock up 5100 stall, 4.10 gears, spool, race seats, 5 point rollbar, no A/C, no heater, no radio and on skinnies 24/7. 90 miles a day everyday.
people ask me if it's boring driving with no radio. I say all i need is that sweet sweet LS1 rumble coming out of each of my two bullets. Damn i can't wait to throew a T rex in her.

 

i never listen to the radio either, hell with a cutout you cant hear it anyway. but i can't live without a/c, you ever been to south mississippi, you'll sweat more than a fat ***** in church.

 

Hey man, who built your T350? And how much was it?? How has it held up?

 

Jl-ws6 I have to disagree , properly built a 4l60e can handle around mid 600 hp. The problem being not to many people have a clue on how to build them. Mine has held up great since this builder.

 

I though stock, the car was rated like 325 or something so how could the tranny not handle 300?

 

LOL Guess my stocker 4L60E wasn't told it couldn't handle 300hp.
