how much is it to rebuild one of these. i couldn't do any of the work myself.

Post by **Dane** » Sat Jun 11, 2005 1:45 pm

I was quoted about 3 grand for a beefed up one for 4wd use. Otherwise about $1500 for a standard rebuild which may not be up for 4wd use.

about $1400 for a full rebuild. transmission places generally won't touch the box if you've done some of the work yourself. i tried it and they refused to work on it

Take it from me, there is no use in just building a standard T/700. Don't get me wrong, some will work fine if your just putting around. But if you want your transmission to last, handle towing, 4 wheel driving and also handle V8 engines that have some sort of a power upgrade then you will need the next step up. We have been building T/700 transmissions for 4 wheel drives for 15 years and build all of Marks 4X4's, Brunswick Diesels and Linquip Diesels Transmissions. We have built over 2,000 T/700 transmissions using both Marks and Advanced adaptor kits so I tell you this with years of experience with the exact transmission in question. We have also become Australian dealers for the U.S. built Compushift electric transmission controller for anybody interested in the heavy duty 4L80E ( 4 Speed T/400 ). It will also run the 4L60E and many others. Take a look at these web pages and you will see some of our handy work.

I don't care if you go somewhere else but Don't build a standard T/700. It won't last long and are not normally set up for the 4 wheel drive diff ratio's and off road conditions.

I'VE GOT A T700 IN A HI LUX WITH V6 COM. ENGINE. I HAVE TROUBLE ON VERY STEEP HILL CLIMBS GETTING ANY DRIVE OUT OF THE THING. COULD THIS BE BECAUSE THE A.T. FLUID IS ALL AT THE BACK OF THE PAN AND THE PICK IS DRY. IF SO WHAT IS THE SOLUTION

Running them over full with fluid is one thing that helps.

Holy crap!

Bold, large and caps? Can we have a mod turn down the volume on this post?

HI-11-UX, people will either read your post or they won't. They'll either respond or they won't. The 'net equivalent of SHOUTING won't make a difference.

I have seen this dropping drive situation before but only on very steep hills, You know! the hill that is so steep that there a bit of a concern before you unleash yourself upon them. It is true that you can safely overfill the T/700 transmission by about 11-15mm and this in most cases is all that you need. If it still continues then you will need to have a custom pan made. Is it any worse going up or down the hill? I would have thought that it would be worse on the down hill as the pick up for the T/700 is towards the rear of the transmission. But if it is on the up hill I would have the transmission serviced replacing the oil filter and checking the filter neck to make sure that it is installed properly.

extreme trans whats your opinion on t400 with stage 2 shift kit.....behind a 350 chev

Post by **Extreme_Trans** » Wed Jun 22, 2005 8:28 am

The T/400's are fine. There a very strong transmission but they do have one down fall when used in 4 Wheel Drives, first gear is very tall at about 2.48 - 1 where the T/700 has a first gear ratio of 3.06 - 1 and an overdrive that is .7 - 1 (30% Overdrive ) making up for the fuel consumption. The T/350 while not having an overdrive has a first gear ration that is between that of the T/700 and T/400 so I tend to lean toward the T/350 if budget is a concern and a 3 speed auto is the only option.

The T/400's first gear ratio isn't that much of a concern on the up hill because you have more than enough power but the ratio becomes a problem on the down hill as the ratio just isn't low enough to aid engine braking.

thanks for the quick reply on the info...

extreme-trans, could you give me the low down on the best trans option for my fj40 with a 350 chev in it? i may upgrade the transfer case and diffs at a later date too.... or is it a good idea to upgrade the tranfer case at the same time? seeing as an adaptor is going to be necessary. i'm gradually getting around the car in a rebuid, i have to go slow funds obviously are a concern. thanks rodney....

With out a doubt the T/700 4 speed overdrive transmission is the best all round automatic transmission that you can fit into any Chevy, Holden or Ford powered 4 wheel drive. It has 30% overdrive for good fuel economy witch also helps the engine last longer because your not reving it so much all the time. The T/700 also has a very good 1st gear ratio that is excellent in the bush and for towing because of it's standing start acceleration but the T/700 is standard form leaves a bit to be desired. If you are going to consider using this transmission then it needs to be specially built to suit the job. As above in one of my previous posts I have listed a couple of our web pages that shows the sort of Heavy Duty T/700 that we build that you might consider. There is also a 4 speed T/400 called the 4L80E that we do that is a top of the range 4 speed transmission that is stronger than the T/700 but it comes with a price tag and 1st gear isn't quite as good as the T/700.

extreme-trans, I have a t400 with full manual valve boby and a few other beefed up bits put in stored at the back of the shed. Can i adapt my 80's t/case to it and bolt up behind the 4.5L ? also what stall converter would be recommended (i assume about 1800rpm) ? alternatively whats the damage for your extreme trans and is it change over or out right ? PM me if you dont wish to discuss prices etc on this site.
Thanks mate

i think t4 and t7 come with 1200 stall standard,i think

Post by **Extreme_Trans** » Sun Jun 26, 2005 12:46 pm

The T/400 Torque Convertor stall speed is about 1400 Rpm while the T/700's is about 2000 Rpm. This stall speed varies with engine size and torque output at around the stall speeds. The 4.5L Land Cruiser Engine has a stall speed of 1950 Rpm.

GUZZLA: As long as Marks 4X4 still have the rear adaptor kit you can bolt the T/400 up to the transfercase no problems but your talking about also adapting the T/400 upto the factory 4.5L Toyota engine, I don't know if there is a kit for that.

If you want an auto trans and want to keep the 4.5L engine then get yourself a 1990-1992 Turbo Diesel A442F Hydraulic transmission, Change the Diesel governor to petrol by removing the transmissions extension housing ( Adaptor ) and swapping them over. Also fit the 4.5L bell housing and torque convertor and it will bolt straight in as long as you have the rest of the factory fitted items such as T.bar Assembly, Consol, Peddles, Cooler, Cooler Lines, Inhibitor Switch, Drive Plate, Drive Plate Bolts, Convertor Bolts, Filler Tube and Dip Stick.

We sell all of our transmission as either Change Over or Outright but in this case you would be better off with the Toyota transmission if you are going to keep the 4.5L engine. I can supply the Bell Housing, Torque Convertor, Petrol Governor and after market Extra Large Oil Cooler with cooler lines if you can find the Turbo Diesel 80 series 1990-1992 transmission.
