TCI: EZ-TCU Transmission Controller Install Basics

Will Vance covers the basics of installing the TCI EZ-TCU controller and wiring harness.

[@uTubed007]

Great video and you picked a very good man to make it. TYFS.

[@REAL4wd]

I finished installation of ez tcu unit on a 6.5 diesel humvee running on 4l80e, its extremely easy, I absolutely love the simplicity and functionality of EZ TCU,good job guys.

[@hellobye102]

was it a 24 volt hmmwv?

[@Gator12]

So I built a Gen 3 5.3 ( carb swapped ) I wanna run the original 4L60E that came with the motor along with the transfer case. Will this system work? If so I’ll buy it.

[@CamaroRick]

Putting one in a 79 Vette, this is helpful to know. Ill replace the white wire eyelet with a hei tach plug.

[@levrone0075]

off topic but great style with your presentation!

[@mysstruck]

Can and how do you share the transmission temperature with the car's ECU?

[@trevorseals6588]

Do you have one for the dodge RFE transmissions? Not much available for the clutch to cluctch 545rfe

[@chevyluv29137]

Do yall have anything for the Dodge 8hp90 trans

[@TheLugnut]

These modules are EXTREMELY SENSITIVE to heat. DO NOT mount under the hood. This left me stranded in the mountains and forced me to ziptie the module to the wiper blade to get me back on the road. I ordered a replacement and removed the harness and moved it into the cab of the truck. Still it goes into limp mode. Pack the module with an icepack and drive for hours. TCI recommended getting a warranty replacement. So that arrived today so I installed it and at least the tow haul works now . BUT STILL GOES LIMP. As soon as it gets warm. Swapped out vss twice at TCIs request. First one was a new aftermarket sensor. Second was a used GM sensor to get me on the road as no one had stock. A third GM sensor is on the way. I don't have high hopes. Icepacks for now.

[@dedrickwashington6219]

Did you figure out a solution? I’m dealing with the same problem and can only drive for a few minutes before it stops showing mph on the handheld and downshift back to first gear.

[@TheLugnut]

@@dedrickwashington6219 I did. I removed the trans control harness components from a spare OEM harness and re installed it in the GM ECU. Reflashed my ECU and have never looked back. I removed ALL TCI components and sent it back. TCI was unavailable to provide me with a working ECU. JEGS was good an gave me a full credit. But it was a shitty experience.

[@kingsavageDKS]

@@TheLugnuthey are you saying you changed the wiring harness

[@TheLugnut]

​@@kingsavageDKSRemoved the TCI system installed my own harness and re flashed my ecu. Then returned the EZtcu to jegs for a full refund.

[@kingsavageDKS]

@@TheLugnut I appreciate the feedback

[@Freedmevr45]

Im running a 6.2 liter diesel with the 4l80, i have the isspro magnetic tac system. How do i make it compatible with the tcu? After tapping into the rpm module but im not getting any indicators of tac signal on the live data screen. WtF can someone help me out here

[@eddube6862]

I changed from an outside prindle switch to an internal switch what do I do with the factory plug for connection to the ecm for range position

[@TheHelene1994]

Can anyone tell me where to connect the " TECH INN/ RPM MODULE" on a 93 silverado pickup 6.5 diesel 4L80E transmission. There is no place to plug it in? Where can I find a tach signal? I dont have a carb, ignition box or any tach output?

[@mironkusnecov5728]

Well I need anything different if I’m running a big block Chrysler?

[@rafiekahmed8568]

Hi do u have any module's that can controll a zf automatic or a mercedes transmission

[@MrGGPRI]

Can the GM alternator TACH signal be used for diesel applications (6.5L) ??

[@mysticdavestarotmachinesho5093]

MrGGPRI Did you ever get an answer about the TACH signal? I am wondering the same thing and see no reply to your question

[@crazielegz4735]

Im getting comm error I Don t noe if is because im using holley sniper efi and hyper spark distributor can anyone help me out pls how can I get it to work with my holley set up or how to wire it to the the holley set up

[@kennytrump6275]

i've installed a 383 stroker motor that has a carb. on it this is in my 97 Trans Am with the 4L60E transmission that came in the car i have bought the TCI EZ-TCU transmission controller powered by fast, am i gonna need to buy the remote TPS unit also or how am i gonna to suply the TPS signal to the TCU controller

[@TCIAutomotive]

Please reach out to our tech line at 888-776-9824. They can walk you through the necessary components and process.

[@samb1944]

Did you get a response I'm putting a 6.0 Ls in my 93 and it with a 4l60E that I want to run with

[@ronaldlewis6062]

I bought the TCI ECU I hooked the gray wire to a switch to ground still no lock up ! Instructions don’t say if you need a power source or not! I have a perfect 4 speed sure would love look up ! Any input! Thanks

[@davemetituk3143]

They are negative switched. But that doesn't mean it will work. The Purple performance mode wouldn't work on the first unit. But it works on the replacement they sent me. Unfortunately the units are EXTREMELY SENSITIVE to heat. DO NOT mount under the hood.

[@kingeyes8938]

Just bought mine brand new and the handheld if not responding it comes on but it stays frozen on the main manu and I can’t do any thing

[@BISONGARAGE]

can i use it on my honda?

[@Kreegers_performance]

wait....if you do not share speed signal then how are you going to drive the speedo on the dash?

[@rickytate9515]

I’m with you on that how can I get my speed on the dash

[@timjipson]

It's mentioned in the next video... kzbin.info/www/bejne/d2PJd2Cep7hnbbs

[@billwidener333]

so what about coil in plug

[@Antonioasus]

I need the same explanation but in Spanish, where could I get it?

[@aaroncolombo]

So i can hook a 4l60e to a gen1 350 chevy thats carburated and all i need is this controller and that deal for the throttle?

[@swschrader1981]

I wondering the same thing

[@ronm4850]

​@@swschrader1981 you would need this part at 2:34

[@Antonioasus]

I need to install this kit on a truck with a 4l80e transmission can you

[@duanehammonds5376]

Don't buy, you'll regret it.

[@Antonioasus]

@@duanehammonds5376 ok

[@jamest.5001]

Is this for 4speed only? What about 6L80/6L90 ?

[@mironkusnecov5728]

In the beginning, pause it when it’s showing the box that it comes in. It says it in the bottom left-hand corner that it works with 6X 6 speed transmissions.

[@9444577147]

can we use this tcu for manual transmission

[@ncs353a]

No only GM automatic transmissions...

[@newnamecomming9357]

haha you are a boss (=

[@ronaldlewis6062]

Made me lol 😂

[@zoeman2958]

One min it reads my speed the next it goes to 0 and my transmission stays on first gear once it doesn't read my speed

[@geoffws6]

I am having the same issue. 93 Silverado w/4L60e and carb swap. I followed the instructions plus I have the tci tps too. I can drive roughly 20 minutes or so before the system stops reading speed and then I’m stranded. TCI could only come up with “send it back”.

[@rustywatts9358]

Their customer service is horrible I email them 3 times. . Nothing. . Finally figure it out myself.

[@duanehammonds5376]

Customer service is non-existent don't answer emails or messages have called numerous times with no reply.

[@mikef647]

To many problems talked me out of it

[@jameslove9540]

talked me out of it

[@H2HGarage]

DO NOT USE TCI. I can not get them to answer a phone call, return a voice message, respond to an email or even a Facebook message for warranty issue. Had to pay for it out of pocket. Now the transmission has 3 neutrals, and I pulling it out to replace with something that has 100% no TCI parts in it at all. I recommend everyone else does the same. No customer service at all.

[@H2HGarage]

@@dickjake7324 same owners now, big surprise.

[@reinaldocruzado8619]

For my life I have no clue why mine wont work.

With the power of today’s smart phones can we save a few hundred bucks and skip the hand-heads?

[@Joe_Blow215]

I feel skeptical about taking technical advice from someone who calls an engine a motor. If that don't know the difference between those two basic things, what else are they confused about?

[@johnparrish9215]

Why do we call a Jet Engine an engine when it has the same number of moving parts as an Electric Motor???? I don't know either.

[@Joe_Blow215]

​@@johnparrish9215 Because a jet engine relies on internal combustion to create power whereas an electric motor does not. Calling an engine a motor is just as incorrect as calling a fork a knife.

[@johnparrish9215]

@@Joe_Blow215 And Steam Turbines are called engines when there is no combustion. All I'm saying is it does not matter in the long run.

[@Joe_Blow215]

@@johnparrish9215 Steam turbines are engines because they produce mechanical power from chemical energy. If the words are interchangeable why don't people call an electric motor an engine? Look, if you want to sound uneducated, by all means continue calling an engine a motor. People who take pride in precision know the difference.

[@johnparrish9215]

@@Joe_Blow215 and a liquid fueled rocket is an engine and a solid fueled is a motor. You are guilty of writing off everything someone has to say over a word slip. Be a bit more forgiving and listen to what they have to say. Then Flame them....lol
