Few weeks ago got a check engine light on and it gave me the tcc stuck code so i bought the selonoid and the on/off switch drove it for like 3 weeks and now my check engine light is on but now i got the temp sensor code and tcc stuck off code what could it be since i alrady replaced both tcc sensors ? Can i still drive it like this has no effect drives the same help......

 

Check coolant in the radiator for contamination.

 

Hmmm ok i will what should i look for oil??

 

No, Gremlins.
Seriously, you post your issue, and want help, yet do not post the codes?
Since, I can not see your H3 in person, I gave you a basic check(common issue), after that, I would need the codes, or you can take it to an auto repair shop and have them replace the transmission, engine, pcm, etc..=Big $$$$$$$$$$$$$ Wasted!

 

P0741 tcc solenoid circuit performance or stuck off

 

With an ECT sensor code?

 

I bouth the cooling temp sensor and installed it and reset the computer hopefully doesnt pop up anymore but i dont think that ect sensor has anything to do with the tcc code coming on its two completely diffrent things idk.....

 

Pray tell.... what is the temp sensor code????

 

What causes the P0741 code?

• Faulty TCC
• Faulty torque converter lockup solenoid
• Internal short in the TCC solenoid
• Wiring to the TCC solenoid that is damaged
• Faulty valve body
• Faulty Transmission Control Module (TCM)
• Faulty Engine Coolant Temperature (ECT) sensor
• Damage of the wiring harness to the transmission
• Restricted hydraulic passages from dirty transmission fluid
