I run a 2.28 front and 4.7 rear with 5.29's on 39.5's. Other than its kinda fun/cool to crawl at such a low ratio I dont think it will ever be needed.

I do a lot of snow weelin and a big tranny cooler was definitely a must for this setup.

I've got the Winters/Rad shifter w/the RAD triple sticks.. I've heard good things about his rail controller as well.

I run the stock shifter for going between P,R,N,D. Then have the RADesign Rail 2 to select the gear. I like how small and compact it is.

Ill see if I can remember to grab a pic tonight. Due to my dual case setup my T-case sticks are back about 6" from stock, I built a plate to cover the original hole and incorporated the Rail 2 into the plate so it sits right next to the stock unit.

Rail Controller this is the controller I use. Seems to be a good quality unit.

Couldn't agree more.. although I've only got one run on mine so far I really like it. You might try the transgo shift kit.. I put that in mine from the get go so I've no personal experience without but Rory at RADesigns highly recommended it.

I guess it also depends on if you're a throttle jockey too

There is just a big jump in the gear ratio from 1st to 2nd, wound out in 1st bogging in 2nd. I agree on running 5.29's but there will still be a big jump. I try running 2nd and 3rd if I need a lot of up/down back and forth shifts.

5.29 gear is on 8.4% more gear than the 4.88 gears I have. That's not worth the money.

An ultimate (2.28+4.7) is completely unnecessary with the auto.

I do. Inchworm adapter.

I assume these guys do too since the thread is about blocking off the fluid from getting to the rear section of the trans.

It won't do it on mine either. I assumed mine was an oddball.

Engine running, shifter in Drive:
12V to Sol1 = trans shifts to 1st, and vehicle moves easily with throttle
12V to Sol2 = vehicle accelerates sluggishly
12V to TCC = engine should stall

Sol2 malfunction: Shifter in "L" - trans will never shift out of first gear.
Sol2 malfunction: Shifter in "2" - trans starts in 1st and eventually shifts to 3rd
Sol2 malfunction: Shifter in "D" - trans starts in 1st and eventually shifts to O/D.

Anybody know the wiring for these?

lambertvr4 I drained my rear pan yesterday, and about 1qt came out. I ran it over full, but couldn't tell you how much because I don't have a dipstick. That being the case, I expected more to come out of the back pan when I drained it.

I don't doubt what you've explained above, but it looks like it's a minor issue. Yes, some fluid will get back to the rear section of the trans, but it shouldn't be a lot. Blocking off the plates far out weighs the downside.

Would you mind measuring the length of your dipstick from tip to flange, and tip to hash marks? Then I'll know for sure what I've got going on. That would let me verify the fluid levels and track what you've explained. I'm going on a ride in a couple of weeks.

I have the shifter in my rig. It works well. I wired it so I can do manual override or have the ECU take over and shift like normal.

Its really pretty simple, the connection on your trans that has 3 wires coming from it is the one you want. All you have to do is apply 12v power to the solenoids to have them work.
perfect! Thanks!

you askin me? or is this a general question about the thred?

Were talkin about the A340 that come behind a pickup, 4runner or taco.....in regards to the wiring, the wires themselves may be different colors, otherwise your lookin at 3 solenoids and 3 wires.

H has an integrated chain drive T-case and shares fluid with the tans.

F has a removable T case and keeps fluid separate.

There is also an A340E

Here is some good info.
