4 Speed Auto - Rebuild / Strengthen In Perth

[nifty]

Now that I have passed the 300 mark , I think it may be time to look at it before it goes kaboom. Any suggestions on who's good in Perth. Thanks in advance guys.

Baileys Automatics in Balcatta, they have been building touch BTRs for years.

About to post the same topic question myself...

Called Baileys today after a few others and without a doubt they know their stuff. The few places I called all quoted around the same... alot more than I expected though on a rebuild/exchange basis.

Any comments from anyone as to whether $4500 + GST is the going rate? And that's not to buy out right, on exchange basis for my 4 spd that currently has no problems.

Anyone with first hand experience with a built 4 spd BTR from Baileys or any others here in Perth I would be greatful for comments... prices, quality of work etc

Cheers

that's a top price dude go for it

I think this is one of the re build jobs where they plate all the internals

[MercuryXr6Turbo]

Yeah he said something about a process they put the metal through which strengthens it... some temperature treatment?!?!!

I see your 4spd is built Jeturbo... what kinda money were you looking at? Was it exchange or rebuild yours?

Cheers for your comments...

im sorry but, your throwing your money away (@4.5K exchange)

there is no special super duper equipment for these boxes. Certainly not that warrants spending that sort of coin. You will find that all the workshops who were doing crazy experimental stuff to the BTR 4speed boxes a few years ago, have gone back to building them to spec, and paying particular attention to tolerances.

The weakest part in them is the Planetary gears, which currently the best option is some cryo treated AU gears, (less brittle). @ around $300 a set.

For your 4.5K, They might do some servo, solenoid mods, (firmer shifting) and build it to spec, paying close attention to tolerances. nothing special!

My box, was in fine working order, I just wanted to do some preventative maintenance, and a couple of upgrades in the weak areas, so I had it serviced, with all clutchpacks replaced with the serrated revised BF plates which hold better, new hi energy bands, and cryo'ed AU planetaries, full fluid flush and replace. for under a grand.

On top of that, the first thing you should do is install a good Transmission cooler, in a spot with good airflow, and preferably an inbuilt thermostat, so it lets the box get up to operating temp quickly.

The trick to making these boxes strong, and last is all in the tuners hands!!!

I.E getting all of the ramp rates correct, fluid pressures, and nice firm shifting. They are able to withstand a fair bit of mumbo, with the right tuner / setup. Mine is withstanding 800nm and just over 300rwkw.

I say save your money and just get them to service the box, replace bands and clutchpacks with BF spec ones, and maybee replace planetaries with Cryo AU's. then go to a tuner who know's how to get them set up properly.

I agree with the above post. Its getting the box to shift hard that saves the box. And in my opinion disabling the S3, S4 solenoids which makes the S5 not needed gives the most solid shifting for box longevity and maybe an older style ED oil pump and Au planetary.

Ask him to give you an exact list of what you get for $4500. Maybe you get some gold plated stuff in there. These old blokes can see a sucker a mile away.

Maybe you get some gold plated stuff in there

hahaha that's what I was refering to when I said "plated"

yes mate mine has had the works done on it with a stall and it cost under3k for my old unit wich was best part nackered to be overhauled.

take the k.y with ya cause its gunna hurt if your seeing those kind of quotes

as above posts said its all in the machining and the tune afterwards

Thanks for the great info ive been pretty cautious of mine , im running 320rkws at 14psi its an everyday driver and yet haven't taken it to the creek. I want to save mine as long as possible so reading info on this particular subject is very helpful. How much are trans oil coolers and what's the fee to install please any info would help ?

[South]

I spoke with Bailey's when they did my trans service, and from what he was saying, they have quiet a few billet parts that they have had 're-engineered' over the years, and they heat treat this that and the other... They have put a lot of time into these boxes, but either way I wouldnt be spending that kind of money on a box either, but that's just me.
