G'day
I started this question elsewhere and was directed here: I've a T700 with a stage two shift kit. When it was initially set up, Trans Man said "here you go, this is pretty right, but you can adjust it a bit if you are careful". Fine. I adjusted the crappy chrome-on-chrome cable bracket so the car dropped neatly into fourth (yes, I know it's an overdrive) at 60kph under very light throttle. It rumbled along at 1250 revs, Everyone Happy.
Lovely. It was great up the hill I live on, was perfect in every way until the bracket slipped out of adjustment and I couldn't get it right again. By the time I got it to Trans Man next day, $800+ of burnt clutches.
Now he's reset it to the standard adjustment, so the car whines along at 1850 rpm (3:36 diff) giving me the sh!ts. If it was a manual, someone would slap the driver in the back of the head until he shifted up.
The engine is getting on for 6 litres - it was happy @ 1250; forget suggesting it was labouring, it seems to be using a bit more fuel at 1850, which bears that out.
PLEASE HELP. If I wanted a car which told me how to drive, I'd use the wife's prius. KNEW I should have found a manual box, but I'm stuck with this auto, so any help gratefully accepted!

Zoomstrange, sound like you have been slapped in the head a little to often !!
Moral to the story, is the same as your LPG saga , dont F%^CK with what you dont understand . Try Ebay for magic wands and a Crystal ball .

lol

if you want to cruise at those speeds and revs get a 2.60 gear set

lol? What's the story with the shit attitude here? I've got a sensible enough question about something to do with my V8's transmission. I was advised to move the question here. It's pretty simple. Car makes enough power to cruise in a lower rev range. Everything but the trans is happy with that. If this is the way some of you blokes talk to people in real life, then it's no surprise you can spend thousands of hours staring at a computer with no friends to bother you.
In real life, I don't get slapped in the head. I come only to Aussiev8 for that. No, I've got a fantastic wife of 19 years and two great children. I travel, I have a great life, and enjoy working on my house and vehicles, none of which are conventional. Yippee. Sometimes these things have problems to solve. I solve them, sometimes with outside help. When it comes to my Holden V8, I was lured into thinking that's what this forum was for. Have a think. Is that what YOU think it's for? Bit less toying with the magic wand and crystal balls or slowly typing out yet more toilet "humour" would benefit this forum.
So, you don't know how to get around the problem, either, I take it. Thanks for sharing that with us.
Any other takers?

shit attitude ? go re-read your first post about your Technocarb issue , what sort of crap was that ?who did you think you were talking to :
I gOT a tecknocarB OnN mi 355 STROKA ad its runnig reache (11:1 at 3000) til Fiv 5000 (rebs - cross this out) revs wen der air/fueal mixre goees tue 17:1 - so its tooo leeen unda lode.
Was this your attempt at some humour ?
What would benefit the forum is you not telling us your sad life stories . just get to the point . and when someone gives a honest reply , try listening ,
Anybody who would own a "Aussie V8" and put as a first requirement , is to cruise the streets at 60 KPH at 1000 RPM whilst getting 100 k/litre is Dreaming .Go buy a Toureg with a V10 Diesel in it , that will do want you want ,(there only $150,000)

More thousands of hours from a person who honestly believes crystal balls and magic wands are useful here. Here's the point: If you've got nothing useful or positive to say - give it a rest!

This isn't be a therapy board for bullies afraid of anyone who doesn't meet with their narrow approval.

Still got nothing to useful to add to the topic? No? Then please leave it to others whom perhaps, do.

Bullies aside, the setup I'm aiming for worked very well but for the small matter of friction in the clutch plates. I've just got off the phone to Trans Man and there is a Govenor Reprogramming Kit on it's way from the US - apparently it's got a range of weights and springs - and will do the job.
More on-topic news once we fit the kit!
Avagoodweegend one and all.

back on the topic guys, 400 your first post really didnt help zoom at all, so lets not start slagging on eachother.

So the answer to the question is Yes, using a Governor Recalibration Kit, you can . . . Adjust Your Shift Points! This is taken from an ad for B&M kits...

"This kit allows you to adjust the MPH shift points of your transmission after it is installed. It is very useful if you have a vehicle that is lightweight, has a low rear end gear ratio or is a conversion. Installs in a few minutes via access through the governor case on the side of the transmission. Fits GM TH-700R4, TH-400, and TH-350."

We put one of these kits in last week and although it needs fine tuning, there are enough spring and weight combinations to get it right. They recommend starting with a single spring change to kick off with (there are 5 springs and 5 weights in the kit, which you can also use to tune the trans to shift later as well as earlier) the thing to remember is that all gears will shift earlier or later so you have to treat them as a group. We went for the earliest combo just to see what would happen and she changes at ~20ks, 40 into 3rd (too early) and 4th appears through the ether somewhere just after that: the shift has become very hard to detect. So in looking to lose 12-15kph from the top shift point, we found it's possible to lose 35 - it would have to be the same for late shifting, so you really can tune any of these trannies to do it your way. In the end we expect to find the kit's instructions are probably spot on for what we want to do. The kit was about $80 and now I've seen it done, I could install it myself at home.
On the economy side, on a decent country run with the electric economy gizmo (torque converter lockup?) on we cruised at around 2100 rpm for 120kph to get a best of 19.5 MPG with a few sightings of the 150/160 mark. Around town, I'll post up what happens for the interested.

"moral to the story" - 1; cars don't have to stay like the factory made them.
2: Cyberbullies know less about transmissions than me. 3: What I have found out and put up here WILL HELP other people genuinely interested.

Now. "but come on" WB5 - you can't eat your cake and have it too; my first post was as "mumbo druggo" free a serious question as you'd like - got zero response; no worries, write it a different way - response. I'm not really interested in pandering to the insecurities of people who know they would get a flogging if they spoke to real people in public like they do here - you ARE FREE to not read every single post ever put up here; and as champy so eloquently put it " dont F%^CK with what you dont understand". What's wrong with being happy that other people aren't carbon copies of you?
Anyone got any more misquoted drivel dreams about 1000 mpg V10 diesels or further slights on my family or shall we just get back to enjoying the cars?

"I'm not really interested in pandering to the insecurities of people who know they would get a flogging if they spoke to real people in public like they do here -"
Well good for you , that is you being the most obvious case in point !!! thats from one Cyberbully to another LOL. Got to to love your self righteous attitude !
Have you ever wondered why most of the posts in this area are usually concerning maximising performance for street and strip applications .? Although good fuel economy is a nice to have attribute , around here its usually secondary to good performance.
Its nice that you have found solution to your issue and have chose to share it with us .
I too have a T700R4 tucked under the bench , ready for the day I want to maximise fuel economy and this may come in handy (Although maybe a 4L60E may be better with new remote BCM , sitting in the glovebox ,electronically adjustable shift points,readily adjustable on the fly for Performance and/or economy)

ProVK

I wouldnt want to be driving a T700 around at lowish speeds in 4th gear, as if it see's too much load without kicking out of overdrive it will cook the clutch/band for overdrive. And loading the engine up by pulling low rpm can make fuel economy worse too...

allports

Years ago the NRMA in NSW did a test on a commodore and with a mid 3s diff got much better econ' round town, cant remember the % but was over 10 just dont remember the actual number. And yeah I'd hate to be buying clutches for the O/D or the lock up.
A lot of feul econ can be gained just by changing your driving style and habits or bad habits. You can do 60 on 2% throttle or you can do 60 on 25% throttle.

You're all woried about the box,what about the crank.I've seen one broken by lugging the motor.

allports

it must have been a severe case of lugging to break a crank....I know how my grandfather drove and he never broke 1. Lol.
Besides autos arent like manuals its a fluid drive with a torque converter. Like a manual will suffer it way b4 an auto will.
