Major Bugs In Ba Turbo Auto

[razorbackfree]

I've got some major bugs going on. If anyone has been through similar problems or knows what's wrong let me know.

Battery is new also.

From a cold start car runs perfect. Gearbox works correctly including sports shift.

Now if I drive like my Grandma everything seems ok, but its because the bug isn't activated yet.

Its usually 15 minutes later, and after giving it some beans, but not even WOT, it first tell tale sign will be a deep thump into third.

Within a few minutes of the thump, It wont change from second to third..

I will then flip back between drive and sports maybe 5-10 times, with a light pedal, it usually goes into third.

But this option is short lived and getting third soon disappears.

If I get third and leave it in drive it will up/down change between third/forth as normal or downchange to second/first.

If in sports it will change up/down between forth and third, or downchange to second or first no problem.

But, when slowing down and it down changes back to second, or I choose second through sports or its kicked down to second.

I'm back at the bloody start again and it wont go back to third.

The only way it ever goes to third is in drive but now it has to rev to around 4900-5200 rpm before it hits third. This is not with WOT or anything, it just gets stuck in second.

As it continually gets worse, soon enough no matter how much flipping in and out of sports it completely refuses to go to third at all. I have noticed if I start driving like my grandma again about 10 mins later, I can sometimes get it to go to third flipping back and forth again, but its never a definite.

On top of this the motor starts pinging as well. Cold it has no pings, it doesn't happen until the dreaded thump.

I have reflashed the tuner with a different tune when hot and it makes no difference to the pinging or third gear working properly.

Another problem associated after the thump is it starts to stall when I pull up. The rev's will be like the transmission is not disengaging or its grabbing and sometimes stalls, again I don't have any problems like this until the dreaded thump.

Used to have a piggyback, it died.

I then had PCM checked, passed, updated and normal tune installed so it would start.

Car was then SCT tuned.

I get no codes!

This box was brought reconditioned and has done it from day one.

Have talked to Auto experts, told me its valvebody in transmission because of no codes.

History - After I brought the car I drove it back home over two days, distance was one thousand kays. Original box used to kick down dramatically with stuff all throttle, but driving home changed gear normally and in sports.

Next day after I got it home, I had no third or forth whatsoever that's why the gearbox was replaced.

Never had any pinging issues or stalls with the old box.

I always swore new computer cars were sh*t! I miss my Torana!

Anyone??

Nothing wrong with computers in cars. Something wrong with the previous owner of the car.

Who tuned it? You never run any piggy back or generic tune on these cars.

If the auto has always done what you say, why wait until now to get it fixed. Should have taken care of it then and there.

Take it to someone who knows what they are doing before it costs you more than what it's about to.

Could be soooo many things. Cut your losses and take it to a shop that knows these cars. Preferably a gearbox place. This could get expensive if you start playing with it yourself.

[EvilDaifu]

That or Ford for a stock BA tune. Auto transmission faults can get awfully expensive to repair considering your BA us probably only worth $9k in RedBook.

[BRK]

No wild guess.Take it to an auto specialist. There are just too many things this could be and fault elimination by repairing is too expensive. Had a BMW that had shift and stall issues. A thousand experts told me what it was - and for a change I ignored them ....... went to the right place and it was two ball bearings in the valave body that had grooves worn in them. The parts were $1 each - we will not mention the gasket / fluid and labour costs BUT it got done and fixed properly.

Find a good shop - there are plenty around.

Don't let a lack of understanding of the electronic systems fitted to the car overshadow the obvious.

"This box was brought reconditioned and has done it from day one."

Box is shit. Get it sorted.

Thx for your comments.

I persevere,15 minutes at a time!

Got a new clutch cylinder towards the conversion at least

I had the red temp symbol flashing up the other day. If you don't know it means if its an auto, the transmission is over heating.

This is a new bug, thermo fans sometimes stay on, then 15 mins later temp symbol. Sometimes I've noticed if I turn the motor off and restart the timing is back 100%.

Then at least I get a decent speed putt timing wise, but transmission still won't go to third, and if I restart it, then pinging is back. LOL

I got under the car and felt transmission temp after the warning light. It was scalding. I checked the tranny cooler just in case and its circulating ok.

I have since taking the front driving light out, because my PWR tranny cooler sits behind it and will soon see if it makes any difference.

Just scored an Extreme triple plate!

Still chasing a tailshaft and still yet to change input shaft on T-56 from 10 to 26 spline.

[JETURBO]

Mate u need to send it into a decent workshop as its become obvious that your struggling with whats going on with the car

[razorbackfree]

Yeah its a bug machine!

10 SPLINE INPUT SHAFT UPGRADE:

23 spline $350.

OR

26 spline input shaft $645

26 spline Triple clutch hub $390

$685 for an extra 3 splines. What do you recon? I don't have the power to justify it, but would be good to know its been done.

The auto is being sent back soon as I can be bothered crawling under the car.

Clutch is being picked up tomorrow!
