The alternator was spinning faster at higher engine rpms

4 new old stock original Spicer ctis wheel valve hose assemblies. With new diaphragms installed. Only one has a banjo bolt you will have to reuse 3 of your old ones. Dont be fooled by the chinese copies on the market with low grade hoses (that hold back your tire air). 860 shipped for the 4 of them.

Real mil DG dpa4plus usb interface with the real cat and ctis software. All you need is a decent laptop running win7 or 10. I havent tried it in 11. Only for A1 lmtv trucks. Nothing to connect to on a first gen truck. 450 shipped. You get the dpa setup as pictured and a mem stick with the...

I have the dash housing and generic tach that fits. First gen trucks have a bellhousing pickup that can drive a tach

I think they are 4 plus usb. I believe you need the usb one for canbus on the c7 trucks.

I will have the original mil dearborn adapters in stock again next week. And if you buy an adapter from me I will include at no cost real mil cat et. It only works on mil engines though. Not on civilian vehicles.

There are two style wtec2 tcms. Physically they appear the same. One is basic and its 12v only and limited to 5 forward gears. The max tcm, which the lmtv uses, is 12-24 and can do 7 forward gears.

The lmtv first gen tcm is max type its 24v

I havent messed with it yet. I use a dearborn ive had for years. I used to use an old cat et clone that worked fine it just fell apart one day. If you have a c7 truck and can’t connect you have to select canbus in the settings.

You can get a nexiq clone for around 200 it will connect much easier.
