Transmission help

Hey guys,

Looking for some help/advice on what you guys would do. 07 tundra SR5 double cab 4x4 5.7L V8 with 258k on the odo(plan on running her till she dies). She’s been running great all year then as it got cold up here this winter and we got some snow it started acting up a little. Had a good snow a few weeks back and I put it into 4wd everything was normal. Took it out the next day and driving to work got all kinds of lights on the dash when just cruising along about 55mph. Pulled my scanner and it was throwing P2757 code. I didn’t notice anything abnormal in the way it was running or feel so I just watched it for a few days and the code eventually cleared. 2 or 3 days ago now I had what I believe is a trans shudder at about 45mph for a couple seconds. Haven’t noticed any big change in shifting but now I’m worried. I ordered a replacement SLU solenoid, fluid, filter and seals thinking might as well just. now after reading others horror stories I’m worried I’m risking bigger issues as i don’t know when the trans fluid was done. I know I have not since I owned the vehicle for 50k, dumb I know, live and learn.

looking for advice on what might be my best course of action. Thanks for the help!

 

Change the fluid, then take your own advice!
