T700 R4 if road driven

400 is the stronger of the 2, but they are both pretty good, but 700R4 if you want overdrive.

Get RVO in Victoria to build up a turbo 700 for you it will be bullet proof. They built the one behind my LS1 commodore, i only had the the one drama with 3rd gear and they fixed it straight away and slapped on the warrenty again. Not forgetting im pumping about 700hp through it. I think for what you will be needing a turbo 700 built by these blokes will be plenty. Top service.

You will loose 30 hp with a T350, 49 hp with a T400, 29 hp with a T700

If ya happy with only having a 3sp then stick with the 400. You should be able to get a bullet proof 400 built for a lot cheaper than a 700.

As mentioned above the 400 is the strongest of the lot, but really if built right you shouldnt have any probs with any.

th400 tougher one of the lot. The th700r4 overdrive can be a bit tall geared with big tyres but depends on diff ratio transfer gears etc.

Is for a truggy pro mod comp rig so l wont need an overdrive it will be mated to a 308 and a gq t/case in a lux. gu locked rear and soon to be locked gq front.

In that case why not a built powerglide or a TF727

Post by **Webbie** » Thu May 04, 2006 10:09 pm

cause 1st gear is too high. then i'll have to change all my ratio's in the diffs and transfer to suit, no thankx.

Stick with the 400, easy to mod and more available.

If you have the power to drive it go the 400. but having said that I think you would blow up a t/fer case before you buggered a t350. I have know people to put the 350 in their drag cars over the 400 because the 400 takes that much more power to drive. ( as mentioned above).

how did you get these figures??? and how does it compare with a manual any loss??

i'd go with a t350 there a fair bit lighter and pretty strong, well enough for a lightweight buggy anyway only thing is dont bother with any of them unless your running a cooler with a thermo pushin air through it they are getting harder to find but i still only paid about 1500 for a fully recoed one which included purchase price

I don't know allot about autos, however I'm pretty sure that with the Turbohydramatic series that the number roughly translates to the amount of torque the box is rated to take. Do note however that the torque convertor has an effect on this output from the engine.

Hot rodders like the turbo350 because it takes less power from the engine than other turbo boxes, and because it is more compact. Honestly, what are you going to do with a 308 to make any of these boxes too weak?

Depending on the bolt pattern on your engine, have you considered the Tri-matic, not quite as low in 1st I believe (2.31, instead of 2.42 or something); but might be another option. If the thing is a comp-rig, i.e. never going on road I would definiantly re-consider a well built powerglide, and of course lower the transfer or diffs to suit the 1.76/1.86 in 1st gear; but if you have a strict budjet I get your philosophy.

for me budget real tight, and have been offerd a t400 for what seems a good price.

Post by A1 » Sat Apr 14, 2007 4:54 pm

you should just get the t350 DRS as stated above hot rodders ie: mallers like the 350 ...as if your rig will ever see actual wheeling on dirt and not the web

Dan

is there a website which lists the approx amount of power loss through the above gearboxes.

Post by **known 2** » Sun Apr 15, 2007 1:08 pm

how strong is the trimatic 3spd? as i'm thinking of replacing the h55 in my 75's for a auto, problem is my motor is a trimatic 308, does anyone make an adapter for trimatic to turbo box? as i'd like a 4spd. it has to be tough as my 308 has about 300hp

or landcruiser transder case to tri auto?
