Transmission

[Sid Dunn]

Just had rebuilt 4l60e tranny put in 93 Suburban. Under engine codes I'm getting 59 : transmission fluid temp sensor open circuit..Does any one know where I should address this before talking to shop? Didn't have this code ever. Where is it? Have heard it's internal. See plug just above pan on drive side but don't remember old tranny. Thanks for any better understanding. New member

Still under warranty?

Thanks Starman. Yea still have one yeat warranty, but me being me I always try to be more knowledgeable than the shop if possible just to not get bamboozeled. I have no check engine light on but when reading it I get the 12 and then 59. Never had that 59. Looks like a 5/16" plug(or metric) driver side a few inches above pan and toward front of pan. Code is open circuit. Is this something I should live with? Think I need to know what that fluid is doing after running thru cooler Appreciate it.

Sid Dun,

 

Here is some diagrams to help you understand what's going on. Chances are the temp sensor got damaged while doing the rebuild. That sensor is within the trans pan, tucked up in the valve body area.

The #1 location on the internal trans harness is where the temp sensor is located.

Anyone know for sure if 295/65R20 will fit on stock Sierra AT4 HD? Nitto's site says that measure 35.12x11.77. Stock tires measure 34.09x10.98. Seems like there'd be enough room but don't want to chance them rubbing. Anyone have same size on here??

it's always best to consult with the vehicle's manufacturer or a reputable tire shop to ensure proper fitment and to avoid any potential issues such as rubbing. They may have more specific and up-to-date information on the compatibility and any potential modification that may required.
