tranny shifting sluggish

Mephisto

These trucks are cursed
out drag racing my friends WS6 last night, i killed him up until about 80, then he blew by like i was sittin still. my question is... my 1-2 shift was kinda slow, and my 2-3 shift seemed like if took forever to go into 3rd... ive adjusted the TV per directions on the sportmachines site, and this has made no difference. is the tranny going, or am i just being paranoid? i also believe im in need of a fluid/filter change.

Is it shifting later and later but still hitting hard when it shifts? If so, the fluid is burnt. Changing the fluid may take care of the problem for now but don't know how long it will be before it gets burnt again. Check the level.
If it is shifting later but sluggish, clutches are shot. Rebuild time.

i went by a tranny shop today just out of curiousity to see what a rebuild would cost... the guy at this shop claimed he did andrew schwartz's ty, and a few others... he was saying something about the tranny's input shaft always breaking on these trucks??? ive never heard about that... he also thought i was out of my mind when i mentioned putting in a 2800 stall... so i told him id come back when the truck didnt drive anymore :lol:

either way im pretty sure my tranny is on its way... does the brian hartman kit thats like 2 grand include a new stall? or is that just for clutches and bands?

My truck is in the shop right now. They said the same thing when I told them the type and stall of converter in it. My fluid got cooked again. They are gonna go all through it and put in a stock converter. I'll post later what they find. Right now the converter is suspect. Cooler was fine, lines were fine, shifted normal until the fluid was cooked. Then the delayed shift. I would stick with a stock converter. The 9/11 helps on the takeoff but doesn't really help after that. The stocker is better for all around driving. Some, not all, of the 9/11s had a shudder. Reprogramming didn't help mine. Generates a lot of heat. Just think about reliability when you do yours.
The input shafts themselves don't break. The drum where the shaft goes into does.
Here's a link where they address that and give a little bit of info.

Go about 2/3 of the way down. Give them a call for pricing info.
Here's a site that discusses causes of torque converter shudder.

It's official. Nothing was wrong with the transmission itself. The owner of the shop was amazed at how well it was assembled and was extremely impressed that I did it.
The 9/11 was full of metal(they flushed it) and the valve body was full of metal from the 9/11. The reason they knew the metal came from the 9/11 was because ALL other surfaces in the tranny were virgin. Everything was like new.
The 9/11 was replaced by a stock stall 2075rpm 12" converter.
So ends 6 months of aggrivation of tranny overheats and shudder.
Hey, only cost me another $1300 for a professional shop to go through it. Kit+converter+aggrivation+3 teardowns(to find nothing wrong)+pay professionals to go through it........priceless.

PS:The shop usually only gives a one year warranty. After seeing the quality of my build and the parts used......lifetime warranty.

The instructions that were used when George and I built our trannys were basic ATSG books and a Helms manual. We also had a video that we followed along with. We first built mine then he alone built his. The parts and mods in our trannys were virtually the same, same clutches, same mods and what not. He used a 10 vein pump mine was 13. He used a Mech Diode I used new sprag with more teeth. Both have same sun gear shell (Beast). He has 5 pinion planetaries front and back, I am using only the 5 pinion rear in mine. We both had full Fairbanks servos but both of us had similar troubles with them. His TV valve is a little bigger than mine. Are you considering a rebuild?

Again with the "we" You really bring a lot of class to the list. Remember you need to answer to things you say or do so be careful.

what would you recommend i get for a tranny rebuild, on a pretty much stock sy? what stall, what rebuild kit etc? lookin for something that'll be able to hold up, if i do more performance mods, and break my neck when it shifts. also, will it cause more damage if i drive it till it doesnt work anymore, cause its startin to slip now.

And thus, which question? I was also not talking to you, I was talking to the person that had the question. Hu Ryde, You are just showing your true colors again. Quit trying to make this BB a Ricer board.

Going to NATS?? Try and win the Roadmaster one, you cant beat a free built tranny.

Umm, Yeah. I'd have to recommend several other options first. And if you did win the Roadmaster offer, go and buy a 4x4 core 88 to 93. Try to get a later model so you know service upgrades are in there and not rely on a shop putting them in for you. I'd keep your original transmission with all the SyTy goodies in tact. (VB, geartrain, etc.) That way, if you get the transmission back from them and you don't like it, you'll have the comfort of knowing you still have your original base to build instead of having to deal with someone else's stuff in your original and only transmission. Nothing is more fun than pulling a SyTy tranny apart only to find all your original stuff modified or exchanged for who knows what. You can't add mods to other people's mods blindly. If you miss a minute detail, you can be hosed. If you get the tranny back and it was everything you ever dreamed of, great. No loss, no risk.

If you aren't fortunate to win the tranny, and in a budget crunch, I'd suggest buying a SRTA replacement from GM with the 3 year/36000 mile warranty. But pay the $250 for the core charge and keep the original tranny. The new tranny comes with a cool shipping carton which you'll need to insist on keeping. If a shop puts it in, they will not mention the carton and either keep it for their use or sell it. Yeah, the SRTA trannies might not be what they used to be, which isn't saying much as far as the quality or strength but at least you have one on GM's dime if it breaks, which it will. They will honor the warranty until they get tired of you, just like most other tranny shops. I went through 7-8 SRTA transmssions before GM shafted me. Most didn't work right out of the box. Why they delivered the truck to me with a new broken tranny is beyond me but they finally said sorry, we can't help you. I said, "I paid for a 3LHM tranny with a warranty that was new and worked, I didn't buy this" They just stare back at you blankly with a smile. "So, what do I do now? Sue GM?" They just smile and say, "You don't sue GM. If you try, their corperate lawyers will extend the case out for over ten years if it takes that long before you run out of money trying to pay your lawyer in the meantime." They also said, " I only know one person that had the nerve to try and sue GM for a breach of contract and he is on his nineth year with nothing still, not even closer to it being resolved than the day it was filed." The only way to get GM to own up to their responsiblity is to die in one of their vehicles just like a 1000 other people for one of the many problems they bury due to the cost of correcting the problem. 2 cents is a lot of money if you broadcast it over the next 500 years. They'll pay when they are forced to or if their image is damaged and they want to look like they care for your safety at all. So, in the meantime, save up your money to buy a nice TC, a nice rebuild or a kit. Build your original or have it done on your own timeline. But you should also make sure that before you go wild modifiying your truck and thrashing it at the track, be sure you are ready at all times to do the job right if you plan on playing zoom zoom with the boys. Nothing will ruin your day quite like your truck breaking. It will happen at the most inoppurtune time and make your life miserable. Theirs a lot better things to be miserable about than a truck but seems like the truck is always there to try proving that theory wrong.

Call me if you have questions, I hope that helps some.
