Hi all. Hopefully someone can help me out. Got the trans flushed the other day as per instructions. Now have an issue with surging at slow speed when cold. Not sure if it is related but that's the only thing I had done. Suspected maybe had an issue with the O2 sensor so replaced that but it would appear to be trans related not motor. Any suggestions. It's not noticed once it's warmed up. Cheers

Is that a BF mark one or two? Being a Fairmont if it is mark one it will have the BTR 4speed, if it is a mark two it will be the ZF 6 speed.

Sorry. ZF6 speed.

The BF mark 1 Fairmonts did have the ZF 6 speeds. The usual advice is to take them to a transmission specialist or Ford dealer etc. I would wonder if it has been flushed with the correct fluid etc.

true it was an option but standard 4 speed

how much is the surge? is it a couple of hundred revs or more like thousands?

Only notice it when cruisin at about 30-40ks.

Was the correct fluid or equivalent fluid used? What was the cost?

so how exactly was this done? because you never ---- ever . ever ever , just flush a automatic transmission. So tell exactly what was done and how?
intrade,

Also do you have a automatic transmission dipstick on this transmission ?
i was writing a whole thing but it could get confusing when the things i write about dont directly apply to your transmission.

The ZF has a sealed transmission with the theory they never need flushing but now recommended by vehicle makers that use this transmission (BMW,Jaguar) and others With the flushing they replace the pan (plastic) which has the filter built into them the steel ones the filter can be changed with subsequent flushes
The whole job takes a few hours allowing to cool,replace fluid and adjust electronically
For me the job was around $500, BF Turbo

ntalke its a lifetime fluid then and vw have similar and toyota as well . A lifetime of the fluid is 6 years vw specify lifetime oem information
as it is the live of the fluid and not the Livetime of whom ever purchased the vehicle logically. i guess you already knew that and yes servicing must be done correct on seald units even checking fluid level is a complete non straight forward procedure manufacturer specs must be knowen and adheered to god knows if i spelled that word right haha .

Wot this poster has asked Kwaka.
And just out of curiosity, was the job done locally, or at an out of tow trans specialist.

this is a video how the transmission fluid is mesured on a newer seald unit automatic transmission. it is a must view for anyone who wants to know how its done professionally, and you will know if your local swaptron guy is talking out his backside or not. from Ntalke you can already see he or she is not in the class of swaptron morons the guy tells every aspect that is mentioned in post 13 and why things cant be done any other way will be clear once you seen the whole video. from post *13 allowing to cool the video shows what is required if you dont have time to allow things to cool toyota made up special tools to do it correctly faster.
As far as I'm a wear it was flushed using a machine, refilled as per manufacture instruction. As it is a zf box there is no dip stick. Oil level has been checked twice to prove level.

I watched that until about 9.5 minutes in when the guy said you have to buy all this equipment to check the oil at the exact correct temperature. It looked to me like the gear they use to fix the warp core on Star Trek and probably just as bloody expensive. I hope Toyota is subsidizing the purchase of this stuff, as they are the ones who designed the super-complex gearbox set up. I work on big earthmovers for a living, and some of those transmissions are just as sensitive to oil level. That's why they are fitted with external sight glasses, with markings for varying temperatures. Before each shift the operator looks at the sight glass as part of his or her pre-start checks. Never a problem.

you need all the gear to check it instantly if you whatch the whole video there is loads more inportant stuff he talks about .
Like if you dont have the gear you must let it cool overnight and have the scantool with oem capability because you must look what the gearbox trans fluid sensor reports and shut the vehicle off when it reached manufacturer spec of fluid temp to check fluid level. no special tools required as the tube in the box is set to this temparature . that is how it is on toyota and quite similar on the vw transmissions where you also fill the trans thru the sump-plug. its not only a toyota thing . whach it all its not going to go away just because you dont wish to know about it.

there is a flaw in that already manufacturer instruction guaranteed dont say to flush it read the comment from ntalke that is probably what the manufacturer instructions say . plus any closed gearbox fluid level are to be done with scantool reading oil temperature of the transmission. look at the video i posted he also talks about morons who do it wrong and its consequences that follow the video applys to any auto trans with no dipstick not just to this toyota he demonstrates on. slight differences but the basic stuff will be exactly what he tells like no room for error on modern suff like i keep telling over and over. post 13 is what should have been done nothing less.
There is a few fluids that meet ZF spec's,Life Guard 6 mentioned here is very expensive others are Transmax Z and Gulf Western SynTrans A full flush gets rid of the fluid in the torque converter as well
If you did not get billed for a new pan it was not done correctly Very expensive box's to rebuild $5/6,000

just whached it i like to flush the torque converter out also on older trans that is easy done by removal of the return hose from transmission cooler , it did not show to do that, ntalke is there a specific procedure to also exchange the torque converter fluid , seems doable diy as they used a normal hand temperature gun. i read often the electronic transmission controller also needs to be informed about new fluids for fluid friction wear adaption reset is what i have seen on scantools so dont know if that ford has any of these in the trans programming .

Someone from the Australian Ford Forum did this
https://trademe.tmcdn.co.nz/photoserver/full/385451872.jpg So I went to a trans service joint and asked for a used ZF plastic sump (free - I had to retrieve it from the dumpster, funny that), then went to bunnings for some 19mm inner diameter transparent tubing (~$6). I measured the height of the oil suction pipe (~79mm, which has an outer diameter of 22mm, hence the 19mm ID tubing above), used an air hacksaw to cut off the oil suction pipe from the old pan, drilled a hole all the way through the oil pan where the suction line was with a 7/8" wood borer drill bit, put half of the old suction line into the transparent pipe and put the transparent pipe through the oil pan to exactly 79mm, then silicone'd it in from underneath with some random form-a-gasket silicone gunk.
This is after I'd completed the service, I didn't think of taking photos while I was making it The next day (after the silicone cured), I thoroughly cleaned and dried the modified oil pan, dumped the old trans fluid and put my home made pan into action!
Filled a clean 3 liter orange juice container (because I had one) with Martini Sint Z Spec ATF, put the suction into the container and started the engine.
The trans pump sucked the fluid from the container into the trans, flushing the old fluid from the oil-water transmission destruction device on the side of the engine, through the torque converter and out of the sump. did a **** poor job of making a good container, but I repeated this process about 4 or 5 times and new clean fluid eventually started coming out of the drain plug, therefore almost all old fluid was flushed from the torque converter. Sweet, no more cold engine fifth gear torque converter lock/unlock/lock/unlock cycling for another 30,000km! Yay, can do skids without worrying about the trans again!
