Those Lokar dipsticks have sure went up. I'm going to wait to see how a manipulated stock one fits my truck before biting the bullet and buying one. I hate filling the trans in my Vette that has one. Such a small dang fill hole.

6bt56, yes sir. The 24v ISB's use an ECM to run the engine. Mainly to control the injection pump etc. You basically use 7 or 8 wires from the dodge harness plus some for the OBDII connector and you can get them to run. It is a lot of wires to get rid of for sure. You pick out which wires go to the OEM cluster and use the stock GM fittings and adapt thread sizes if needed to get the stock gauges to work. Definitely not as simple as a 12v.

I had to use a lokar dipstick on my vette, tried every way to use the stocker and just couldnt get it to fit. The good thing is that once you get it full you dont have to do it very often. I didnt have a dipstick assy for the allison I am using on the crew cab but I had the stock replacement one that I bought for the 4l80e that wouldnt work in the vette. Its going to be tight to the firewall also and the bends just werent in the right spots, I tried heating it and adjusting it a little and that didnt work either. As an experiment I measured the overall length and cut both ends off and used a piece of silicone oil hose to connect them and I think that will work pretty slick. The dip stick goes in and out of it just fine and no tiny hole to try to fill it through. Nice project by the way COS!

84ChevyguyID - Thanks. Filling up the trans was a PITA, but what I didn't care for is that on the factory dip stick you have your "cold" and "hot" range and on the Lokar it only registers when your in the "hot" range. That is if I had the correct OEM dipstick, not sure since I bought it used.

Your project us coming along nice as well. I think Mud Lake is off of I-15 on the turn off to Rexburg and St. Anthonys correct?

84chevyguyid · 03-09-2014, 10:24 AM

Yup, exit 143. Rexburg is east, Mud Lake is west. Where in MT do you live? Hey, found a pic of the dipstick. I think I will build some shielding around it to keep some exhaust manifold heat from cooking the handle. Its further away than it looks in the pic. I couldnt go any longer with the length of the dipstick.

COS399 · 03-09-2014, 01:05 PM

Looks good and I'm sure it was a lot cheaper. I wrapped my exhaust down pipe up to the transfer case. Of course that wrap is kinda pricey as well. I am off of I-15 just north of Shelby. We ride out at St. Anthony a few times a year and most of the time we go down the Interstate and turn at the Mud Lake/Rexburg exit, but once we went the "scenic/tourist" route east of the interstate down to St. Anthony. It's a lot closer than Glamis and Glamis is too hot after February.

What do you ride on the dunes with? I dont get over there very often anymore. Back in the good old days we used to ride our sleds on the dunes all the time and that was a blast but now they are closed through the winter. They are fun on the 4 wheelers I have but only when it rains and it doesnt ever seem to rain here anymore

COS399 · 03-09-2014, 06:09 PM

We ride Sport ATVs. Last year we rented a RZR for a day. I remember in 2006 it seemed like it rained every night we were there and made for some good dune riding. This past July we were about a mile from camp and got hailed on, managed to make it back to camp, changed clothing and went back out to enjoy the wet sand. We were about in the same spot when the rain and hail came back. After that we decided we would stay for the evening.
