code p0751 shift solenoid

[bjballar41]

i just got my tahoe the other day and the guy said he had the solenoid changed out just the other day and now its throwing this code. do you think it needs a new one? or maybe cleaned off or it came unplugged. it does have a shift kit in it (dont know much about it) and also had gears changed to 4.88 in the rear. trans is stock besides shift kit as far as i know.

year make model 4x4? engine size?

 

[bjballar41]

its a 2000 but old style 4x4 but front isnt hooked up engine is a 350 and z71 but doubt that part as far as i know.

If you have an SES light on could be your solenoid but if it was just changed i would start by dropping the pan inspecting condition of fluid and how much metal is in the pan/ magnet. Guy u bought it from couldve just cleaned all that crap out though. Next thing i would look for is burnt clutches. New or rebuilt tranny. I personally would never put a shift kit on unless the internals were upgraded.

 

[blackdiamond]

Sorry, inspect the condition of the in pan harness. and considering the front isnt hooked up i would question the maintenance history of the vehicle also.

we cleared the code to make sure it was the solenoid how long does it usually take a code to come back on it hasnt yet and ive driven it probably 3 or 4 times pretty good distances

Usually right away if the problem is present. could have been clogged... how does it drive now?

 

[bjballar41]

drives fine ive never driven anything lifted with different gears or a shift kit but when i first start it takes it awhile to shift but it will shift usually between 4 and 5 but doesnt seem to have any problems shifting

4 and 5? rpm? How does the fluid look/ smell?

 

[bjballar41]

ya 4 and 5 rpm. and i havent had a chance to look with all the rain we have been getting. im gonna try and take a look today.

 

[blackdiamond]

RAIN? LOL. WHATS THAT? I wish it would rain here. Yep, just let me know what you find man.

 

[bjballar41]

went and checked it didnt smell burnt or anything fluid looks clean wiped it off and it was kinda a redish color with black from the rod.

 

[blackdiamond]

just ride it out. see if the problem corrected itself.

 

[bjballar41]

i think it has hasnt come back on since yesterday

 

[blackdiamond]

cool keep rolling. update as necessary

 

[bjballar41]
