Why would you need an adapter (24-4GT) to bolt a gear driven case to a 2.4L 5spd? <img src="/forums/images/graemlins/confused.gif" alt="" />

Also, my understanding was that the R150 to gear driven reduction box adapter in the V6 Tacoma "kit" was the same as the old "V6 adapter" (3.0L) and that just the adapter to go from the reduction box to the Taco case was the new part... <img src="/forums/images/graemlins/confused.gif" alt="" />


Normally a W56 tranny is put behind the 2.4L motor but a small number of trucks in 89-95 came with a G58 tranny and chain drive tcase behind the 2.4L motor. The 24-4GT adapter is a standard V6 adapter plate but with a special 26 spline coupler. So the 24-4GT is only used on rare trucks where Toyota installed the G54 tranny behind the 2.4L motor.

It's my long term goal to try and get as much of the info in Marlins head on the web site as possible. Before on the web site just a couple of adapters were listed and then when you called up the proper parts were chosen and shipped based on what you had.

I have started working toward creating different part numbers for each different kit. Kit a my be similar to kit but with just a small change in the shift forks, or sleeve or something like that. I personally think different kits should have different names or part numbers. In time I should be able to add more descriptions to make clear what is in each kit and what transmission and transfer case it's designed to work with.

It's my hope that in time I will be able to redesign Marlins web site and document all the little things that make this seem like magic. Think of this process as something like trying to plug Marlins brain into the internet for public access.

Already in the works is a Transmission and Transfer case reference library that will cover all the common transmissions used in Toyota 4x4's from 1979 to current. There are a lot of different parts to cover.

Just a little tidbit that I learned recently, The 95.5 and later AUTOMATIC Tacomas and 4runners with V6's use the same transfer case as the 5 speed trucks, only the adapter is different. There are a few different transfer cases, they're all chain driven, but some of them are manual with no switches on them for the ADD, some of them are manual with switches for an ADD axle and some of them are that ONE TOUCH GARBAGE with the servo that engages the front axle. As far as I can tell, they'll all interchange. Something else I've discovered is this, if you have a transfer case that came off a truck with manual hubs, they appear to be NON-syncronized...meaning if your hubs are unlocked its not possible to engage without coming to a stop. If you have the SAME (appears the same physically, with the exception of having the ADD switches) transfer case from a truck with ADD, they appear to be syncronized. I recently put one of these in my Prerunner with manual hubs. I can be driving 60mph with my hubs unlocked and pull it into 4WH with no effort...no grinding. ANYWAY, just thought I'd share this. Might cause a couple lightbulbs to come on for someone. <img src="/forums/images/graemlins/smile.gif" alt="" />

You just contradicted yourself. Conventional wisdom says that you can not put an auto T-case behind a manual tranny and vice versa (with regard to the 4R and Taco drivetrain). Plus from what I've read, the drive shaft lengths are different.

AH my friend, but you are the one that is wrong here. I JUST DID IT. And you are correct, the automatic trans with THE SAME transfer case on it as the 5 speed R150 is 1 1/16" longer. I just failed to mention that. ALSO the automatics use a different mount because the adapter section (which is where the mount bolts) is different. I had an R150 from a '96 Tacoma and an Automatic from a '99 4runner...the transfer cases were EXACTLY the same, the only difference being the '96 had plugs installed where the ADD switches would go because it was out of a manual hub truck. I promise. Perhaps you're thinking of the earlier toyotas that had the passenger side drop. THOSE automatics used a totally different type of transfer case. I got one of them too. I wouldn't have posted that information if I wasn't sure I was correct. I promise. <img src="/forums/images/graemlins/smile.gif" alt="" />
