Re: Tranny rebuild
Screw the rebuild. Research a 4l80. Itll keep your truck from hemorrhaging cash in the future. The stockers just arent good enough to handle STOCK hp numbers let alone any modding.

Re: Tranny rebuild
Stripped rear planetaries, broken sun gear shells, flipped sprags, busted pistons, burnt clutches in the 3-4's, broken 2-4 bands, broken input shafts, output shafts, input drums.....I can go on. If you drive it like you have some sense, you CAN make it live. My phrase is "if you want to drive it like you stole it, go 80e". You can brake torque them for as long as 45 seconds and the temps will not get over 170. Do that with a 700 and watch how quickly it smacks 230 deg F. If you are willing to do what Mr. Gerber says in that post, then definitely go for the 700.
TV cable provides line rise in coordination with throttle position.
Try this. Push in on the adjustment button and grab the slider nipple and push it toward the driver's side about 1/8". Drive it again. If it shifts better, then you are probably OK. If you do that and it's still slipping or shifts really late and mushy, the trans clutches and or seals are toasted.
A really well built 700 is $2500+ just for the trans. And you still get a 700 in the end. You break a $2500 trans and say screw it, pay $1450 for a local rebuild. Figure $600+ for cheaper converters your at what?.....$4550? For around another $450 you would have 80e, kit, controller and converter (depending on which converter you get) and be good to over 750HP easy.TYTILIDIE said:
700r4's, 4L60e's, 4L70e's have an unusual shift characteristic all there own. WindedV6 did a really good writeup on how to make one live. Do a forum search for WindedV6 and "downshifting". Hopefully that will narrow the results. Because of the way the 700 shifts, it leaves them VERY prone to failure. Couple that with cast aluminum and stamped metal parts that are bearing the load and it doesn't leave much tolerance for playing.quicksuv said:

Re: Tranny rebuild
I'm not bragging here, I know that time is NOT on my side, however I've been racing my stock 700 for 3 years now. Purely guessing at maybe 200 1/4 mile passes. Never abused on the street with manual down shifting or whatever. All "abuse" has been confined to FT up-shifts. The thing still works, still shifts hard, oil is clear with no smell. I'm afraid to look in the pan. :rotf: Last time the oil was changed there were some very small metal particles, will look again a bit later this spring when the big cooler goes in and the oil gets changed.

Re: Tranny rebuild
My truck was off the road for over two years after my second 700R-4 went (total crap rebuild but it was cheap and I wanted to drive the truck). I was still making payments on it at the time too so that made it even worse. Nothing like making a car payment on something that you can't even drive... I changed jobs and moved so, I did have the cash to get it done *right* so it stayed back of the garage. I sucked not being able to drive it but, I wasn't going to try my luck with the "cheap & easy" route again. Everyone knows the old saying that "you get what you pay for"...

Re: Tranny rebuild
To the original poster hasn't responded to this post. What you do with the transmission is really upto your plan for the Ty. He did buy it for $2000 and it has 196K miles (smoke as well), so a $5000-6000 4L80E might not be on the top of his list.
If you going to keep it stock or simple mods, you can get away with a 700R4. I would seriously think about do one of the $2000 transmission options form one the SyTy vendors, it save a lot of hassle later. If you have big plan for your Ty (11 or better, seriously think about the 4L80E.
Often a $1200 local rebuild is mostly labor.
6-8 hours Rebuilding'/Cleaning
4 hours R & R the transmission
Remanufactured Torque Converter ($200)
You might be getting $200-300 worth of basic (or basic performance) parts and they probably don't even pull everything apart to clean it.
A warranty is junk, if continue to break it. ONce they fixed, after second or third time they tell you to get lost. I don't care if their 400, 500, 600 hp Corvette last years on that transmission. A it probably wasn't on slicks, B People exagerate hp, C SyTy's makes tons of Torque, torque is really what kill transmissions, D AWD is hard on the transmission than 2WD.

Re: Tranny rebuild
So your saying the engine AND the trans are toast and he paid $2000 for the whole truck?I'd say 700r4 Basic build with a STOCK torque converter, take it easy until he gets the engine done so he can see what he's getting into. He may end up getting rid of the truck.

Re: Tranny rebuild
i agree with you. i was worried too about exploding my 700 but only because this forum has made me paranoid. i boost launch mine daily with no problems. 380 hp on the last dyno run. rebuilt the tranny myself a couple of years ago. it was in great shape when i started too, if the tranny wasn't already out of the car i wouldn't have even bothered rebuilding it.
a 4l80 is a nice tranny but my foot has done whatever i want it to including standing on the gas and the brake at the same time... many, many times. no breakage. and oh yea my $5000 is in the bank making more money.
there is a point where you put in a 4l80e. i'd be surprised if over 20 trucks need one.
save your money.
