Hello all have been struggling to get my first gear lock wired correctly...
does any one have this done on a 98 classic?

getting fed up of it shifting...

why did they make the transmission like this in the first place?


thnx!

Brett

Didn't even know you could do this I would love to see a write up on this I hate that I can't choose between first and second

I KNOW there is a write up somewhere, but if you remove the trans control unit, or its fuse, it won't shift out of 1st until 4500rpm(pressure shift).

I found this:

thnx for the info all,

not looking to spend 150 on a switch that i can wire my self... am just looking to see if any one has this done on a 97+

seems that most have it done on older models

im pretty sure i have the right wire (the yellow one) if i have the switch turned on (cutting power to the TC) it should in theory stay in first right? Or do i have to have a second switch to control the solenoid?
-side note when i do have my switch on and try to start the jeep i get nothing (it doenst start)... so im doing something in there

specific pictures would be great

thanks again!

sorry buck i know u put some effort into me already but am still struggling

On *most* AW4 transmissions it has a built in function to lock into first gear. While stopped, shift from D straight down to 1-2. This will lock it in first gear. Works on my '99 and I know people who have confirmed it to work on their 93 and 95. The only problem is without a big switch reminding me of it, I often forget I can do that lol

If you want to have it locked in first gear all you need to do is put a switch in the power lead to the #2 solenoid. You simply flip the switch to off and cut the power to it while in the 1-2 position.

Doing it this way still force shifts at high RPM's. Doing it on the solenoid eliminates this and will stay in gear no matter what. This is EXTREMELY nice on a steep decline while in 4LO. There are many times that the engine is doing most of the braking at very close to redline in my rig and an up-shift could be very disastrous.

Pulling it back to 1-2 gets you 1st and 2nd, but my '96 doesn't shift into 2nd until 4500 rpm.
