#29 of 98 No "tow package" blues
Jun 27, 2007 (4:55 pm)
I have a 2006 V6 Tacoma Double Cab 2wd with TRD. I want to kick myself for not getting it with a tow package. Even without the constant need for towing I'd rather have the extra goodies for better performance.I have to tow a 19' travel trailer with a dry weight of 2900. Is there anyway I can get the tranny cooler, oil cooler, and 130amp alt and install them myself or have someone else do it?Toyota parts dept. says they don't sell those parts as accessories and if you don't have a tow package you're out of luck...told me to get another Taco with the package. That was a dealer in So Cal 909.Other inept parts workers don't even know what I'm talking about. One told me that a Taco without the tow package can tow up to 5,000lbs. What can I do? I went to the dealer yesterday and looked at the tow package Tacos and saw that the installation of the tranny cooler is pretty straightforward. Now the oil cooler was different.I don't know if it's an internal cooler within the radiator or something like that. Also if I tow...does it need to be in 4th gear so as not to burn out the tranny?For those in So Cal, I have to tow north up the Cajon Pass and then through the desert on the 395 and up Tioga Pass.I want to make sure my lil Taco can tow through this.

I know what you mean about the parts and service people knowing jack squat--that's been true with Nissan too. However, I called a transmission shop and asked them and they said that an aftermarket transmission oil cooler could be installed, but they didn't think an engine oil cooler could and they do not recommend changing the alternator from 110 to 130. For one thing, it doesn't make that much of a difference to go from 20 amps higher, for another, putting in an after-market alternator in can apparently mess up the electrical components in the vehicle. Personally, I would talk to a few more transmission and repair shops that deal with trucks instead of talking to the dealers--they just seem intent on selling new cars and not providing good information and service on the ones already sold. If you find out any more details, please post them as I am sure we would all be interested to hear more on this subject!

I know of this place in Corona,CA called Hayden Automotive and they make tranny coolers including some of different ratings for the 2005-2007 Tacoma. I'm going to look into that. The part number is #402. I think PepBoys had it for $29. Those guys at Toyota gave me different answers from dealer to dealer. They didn't know what gear is best for towing. They told me to refer to the owner's manual which I did but it say's nothing about it. I told them my old Dodge recommended towing with the overdrive off. Then this Toyota service nut said, "well if Dodge says to do that you probably should with your Tacoma." Don't know if he was being sarcastic. They don't know jack.I really would like to have an oil cooler too. I bet that could really improve performance. Do you know if the oil cooler is internal like in the radiator? Would you trust the stuff from JCWhitney? They claim to have some after-market oil coolers for 06 Tacos but I don't know if that's possible or trustworthy info. I see what you're saying about the alternator too. Do they put in a heavier duty alternator to keep up with providing power to the trailer lights or am I missing something? Never quite understood why a heavier output alternator for towing. I'm going to start off with the tranny cooler and let you know how the installation goes. I wish Toyota had tow accessories they could install for you. At least you'd be more confident in the results. I wish they had more informed service techs. Thanks. I'll keep you posted.

I was told by that transmission shop that the engine oil cooler would be a little box near the oil dipstick... I tried looking for it, but not being a mechanic, I couldn't tell what I was looking at. Maybe if you compare your engine with a truck that you know has one, then you'd know what to look for. I did get the impression that the higher amperage was because it was powering a trailer, but several people, including a few on some car forums said that 20 amps wasn't enough to make a big difference.
Haven't heard of JC Whitney, but would recommend doing as much online research and posting on forums like this one to ask about other people's experiences. With how uninformed the dealers are about their product, I would swear they just drive go-carts themselves. Good luck!

Does a bed entender require drilling into the composite bed liner? Thanks.

It is my understanding from a transmission person that a transmission cooler can be added to any vehicle. All it is, is a small radiator that is attached infront or off to the side of your vehicles radiator. I have one installed on an old 1978 Forf Granada which burned transmission oil due to heat after it was installed and the transmission overhauled I had no problems with the vehicle. As for the oil cooler if I am not mistaken its the same thing. The reason a larger amp altenator is used is because some trailers have electric brakes which puts a strain on the electrical system. If you do not have electric brakes then I would not change. Hope this helps.

We just got back from our trip in to the mountains with our toyota taco 4x2 v6 w/ towing package. The truck did great. We borrowed a trailer that weighed in at 4900 dry. We drove up to Mt. Hood which has a pass summit at around 4000 ft. and a pretty steep grade for about 6 miles. We waited to fill up the fresh water until we got to the top, but our route brought us back down quite a ways and then back up, didn't notice the difference really. We were able to go up the steep grades at 45 mph without pushing it much. Hanging around 3000 rpm ( no constant shifting into low gear) We probably had around 1000 lbs of gear and fluids between the truck and trailer not including us and the 20 lb kid. The only thing I am considering is adding some leaf springs for stiffer rear suspension. I think we are pushing the limit a little, and would recommend slightly less weight (maybe around 4000-4300 dry) only so you could load up more gear and fluids more comfortably. We are going to go ahead and buy the trailer w/ 5100 lb dry weight and deal with it, we really like the trailer. In a couple of years when we pay the truck off, we are going to buy a slightly used 4-runner w/ v8 which should give us a little breathing room.
We got a Reese 1000 lb hitch w/ weight dist. and will be putting a dual cam sway control on new trailer.
Does anyone know if the taco towing package has larger wiring to charge the house batteries quickly? And any tips on getting a generator. I am thinking of starting out with just a converter along with two 6 volt house batteries for quick 120v use.

This is very helpful, gandalf & bushsm 135. Thanks for sharing this information. I will definitely be installing a supplemental transmission and engine cooler, as well as a heavier duty battery because we expect to tow up to 5,000 lbs. (total tow weight, cargo included).
Really glad to hear that the Taco did so well.

I have an 07 prerunner,4door,TRD with factory tow package and 5000 miles. My first chance to check highway milage I pulled an open trailer with motorcycle total 800-900 lb.
Ran 70-80 mostly , some flat (florida) some mountains Ga , NC . Worst MPG was 16.5 Best was 20. Truck ran as if trailer was not there on the flats. Going up hill in 5th the tranny would come out of overdrive then down to 4th. Never needed 3rd.Never ran hotter than normal.
#38 of 98 Brake controller wiring
Aug 01, 2007 (11:20 am)
I just bought a 2007 Tacoma with tow package and took the fairly new brake controller off my 4Runner. Question about wiring the controller to the Tacoma: the jumper harness provided by Toyota has 5 wires and my controller only has 4. As the controller was previously installed by Cap-It, they did not leave me with instructions. Unfortunately they did a messy job and I thought I could tackle installing the controller in my Tacoma myself.
I can match up 4 wires, I think. According to Toyota's diagram:
1. Black-red: fused trailer brake controller battery feed matches to the one labeled "Battery" on my controller
2. Green-white: vehicle stop lamp switch to brake controller (input) to "Stoplight"
3. Brown: trailer ground to "Ground"
4. Red: trailer electric brake feed from brake controller (output) to "Brake"
5. Green: Headlamp switch to vehicle trail lamps to ???
Can anyone help? Thanks
