I’ve installed that 620-112 setup on a lot of D2’s and had either 1-3F improvements or same as OEM results.

It’s not really supposed to a temp changer or performance upgrade vs a reasonable priced/reliable replacement for the 03-04 setup which is a one piece unit. I’ve installed it into older 99-02 setups where the OEM blade was about to break a blade off. Perfomance is going to vary depending on the fan clutch being used standard/HD/Severe. I have never used the Hayden 2991, as I’ve just used the Made in USA Severe/HD unit from Auto Zone (they used to offer a torq flo unit that was like extreme severe duty, but it’s now listed as just a HD unit).

 

It was bound to happen sooner or later. I removed the CD changer from under the passenger seat and donated it to an electrical recycling outfit.

Now I have a cord that goes to the radio unit. I was on the net the other day, and their are outfits that all you need to do is plug in a new cord at the back of the unit, to some audio-link box in which you can play your music through your iPod/USB.

 

I picked up the grom unit and it has been working great

 

 

Yeah, Grom!

 

Just unplugged and removed?

 

Some people say adios to the interlock completely, but I’ve seen the aftermath when a passengers handbag snags the handle and it goes from 4Hi to N then in the panic that follows someone bumps it either back into 4Hi crank snapple pop, god forbid into 4Lo when a rather larger jolt is felt followed by a lovely explosion of internal parts & outer casing. On a strictly off road truck okay maybe, but on a LR used on the highway I’d just get an 03 linkage (if you don’t have a CDL) or an 04 linkage and fix it properly by bypassing removing the inop unit from the TC, and using the newer external stye found on 03 or 04 linkages. Might be a few $$$, but it’s way better vs what “could” happen.

 

My 04 is hard to shift.
I am getting around to fixing it soon.
Is there a preffered way?
Does the 04 have 2 solenoids?
Thanks
