i understand nobody makes anything to change the low gear in the tacoma transfer case.

what im wondering is if anyone can post some pictures of the internals of the case because im wondering why a different gearset cant be added.

does anyone know of an alternative bolton case that would allow the use of higher gearing?

thanks

chain driven, yeah marlin crawler has the crawler gears for it, 4:7, inless you have some push button which i dont know about.

dfoxengr

no my 96 is a lever operated t-case.

anyone have pics of the internals?

Marlin would be the best source for crawler gears.

right, im just looking for the most cost effective option.
plus i dont want to have to mess with driveshaft lengths or moving things around.

basically i really just want to get some pics out of this thread.

thanks.

I don't have any pics of the internals, but I did install 4.7 marlins in my Taco last year and It wasn't that difficult for me. My truck crawls its ass off now. I couldn't see adding a doubler anytime soon, atleast not until I go SAS. There is just no need IMO. Remember, lower gears =more torque at lower RPM's which=axle breakage etc., at least if you wheel aggressively like I do.

The 4.7's make it considerably easy to go through harder trails with relative ease and more control than a stock gearset. My rig has the 2.7 litre plant and the lower gears make up for that lack of ooomph that I had with the larger tires, especially at higher altitudes. Get em' trust me you won't regret it.Marlin is the BEST!

i thought that tacos were gear t-cases and couldnt be adapted to work with marlin chain-driven gears...?

the reason why you can't change the gear ratio is very simple, the chain driven T-case uses a planetary drive system and nobody makes aftermarket parts for it, because it would be too expensive. The older gear driven T-case has a typical gearset. There are several ways to have different gear ratios with the newer T-case design. You can add a Marlin Crawlbox to give you a lower range and recently Inchworm came out with a drivers side drop gear driven T-case that will fit that uses the same gearset as the older design, but with a cost, you lose shift on the fly.....


Can you explain how you installed those gears in a 2000 Taco T-case?

dfoxengr

yes another cost being the cost as well. ha.

BruceTS

To do any mods cost $$$$...... oh well, I was seriously thinking about getting an Inchworm T-case, then get Marlin to modify it for his disconnect gearset....

dfoxengr

right but im an engineer, so i like to design stuff a lot myself if possible. just checking if this is a possibility for something custom i can do.

Why is that Bruce? My old '87 22R-E truck had the chain drive transfer case but as long as the hubs were locked I could shift in and out of 4WD High while moving. I am curious how an ADD front end would be any different.

BruceTS

I'm talking about the gear driven transfer cases, they are totally different than the newer planetary drive systems.

With the newer T-case design, you can easily shift from 4Lo to 4hi, then into 2hi while moving, the older design you need to come to a stop to go from 4lo to 4 hi, otherwise you grind gears. In any case you can shift from 2hi to 4hi with any of the T-cases, but it's not recommended for the earlier types, especially if you forgot to lock the hubs....

That's why I'd like to know how you can put a 4.7 gearset into a Taco chain driven T-case, they don't fit. If you don't understand why, click the link in this post.

post pics of internals of v6 chain driven tcase please...
