I was able to reserve spot #8 on my work computer just now. I wasn't able to do it on my ipad from home yesterday. I'm taking the M715 camping this weekend with my Trail Life troop. The March camp out every year is the learn to drive a manual transmission event for the young guys. The M715...

I have the Compushift controller. It doesn't need a tach input to work but it does need one to show rpm on its display. I also have a Dakota Digital gauge cluster which does need a tach input. So, I have the TCM and the gauge cluster both getting the signal from the Dakota Digital converter...

Thanks for setting this up. I hope to make it Friday evening with the Cowdog.

I have a 4L80E in a 1987 Suburban that looks like a CUCV. I can’t think of anything different between them concerning 4L80E installation.

I forgot about the oil pump drive way. I had one of those and tried it first. It leaked oil out of the plug housing when I test ran the engine. Then my serpentine belt drive vacuum pump froze up soon after. I went with a CUCV vacuum pump and promptly forgot all about the speed sensor back...

It is certainly evident who has made a 4L80E work in a truck it wasn't meant to and all we learned making it work. Neat to read about different ways to do the same thing too.

I was typing while you asked your question about the stock CUCV tach signal. It was for the STE/ICE diagnostic suit case they used back when the trucks were new. Think all analog OBDII with no real information from a 4 digit digital read out. I went to the trouble to find one that worked and...

As pointed out the CUCV alternators have a tachometer signal already. Some vacuum pumps generate a signal as well. But, that signal might or might not talk to your tachometer or TCM. Your transmission control module should generate its own engine speed signal because it gets the input shaft...

The shift linkage is just a metal rod connecting the column to the transmission. I suggest you check each end for slop and maybe adjustments.

So do you want to only have a single key or keep the double key thing? Pulling the lock cylinder from the column is easy but does require a few special tools that your local auto parts store will probably rent or loan. Pull the cylinder and put in a stock keyed one and you are set. Or, pull...

Did the same key work in both the door and ignition before? They came from the factory as one key for everything.

2 weeks of research has taught me some things I didn't know before. I have a 1985-1993 Delco glow plug controller on the truck. This is the one that is gray in color, has 4 leads and doesn't go into the cooling system. GM went to the black 3 pin controller when they went to the computer...

I saw on old documentary about the Market-Garden operation over the weekend. Sure were a lot of on fire gliders coming in to land. Once of fire, they sure burned fast.

The submarine people I have know always point out to me that there are a lot more airplanes in the water than submarines in the air. They kind of have a point.

Swapping a better column as mentioned above is the easiest and cheapest way to get what you want. Tilt wheel looseness and wiper switch activation are the things to look out for. I think I am pretty good at working on stuff but those stupid wiper switches have always gotten the best of me...

I have done the dry gasket way, the rtv with gasket way and the no gasket with just right stuff method. All work great. To me the thin metal valve covers are the problem. They bend if you look at the sideways. I have found that the ball end of a ball peen hammer whacked against the head side of...

The banks kit was designed as a stand alone add on kit. Besides turning the fuel up just a tad, nothing else is meant to be changed with the engine. I think Keith is right on with the initial timing of your IP a bit too advanced. The cold start advance solenoid being on just makes it more...

I forgot about even asking about the timing. Good call Keith. What is the timing mark at?

Yes, the -34 manual covers removal as does the HMMWV -34 manual. To me the hardest part is the one arm push ups required to do the job. Some kind of powered socket driver makes this a lot better. Pull the intake manifold. Pull the fuel injector metal lines. An 11/16” crow foot wrench is...

There are two kinds of white smoke: Fluffy white that has an antifreeze smell. Normally this means head gasket issues. Dirty white with a diesel tint to it. This means not enough heat. If you are getting a continuous cloud, not just a puff at start up. Then once it is running, you are not...
