Blown 346 Posted May 31, 2018 Report Share Posted May 31, 2018 As most know I just had my trans rebuilt due to a broken input shaft. The truck has been fine. Tonight i lift the hood and notice the top of the trans dipstick hold down is totally gone. Just the dipstick remains. The plastic and all gone. I had the dipstick pop out once while it was locked down. That happened after beating on it. Main question is, how the hell can the whole top of the dipstock lockdown vanish right off the stick. I can understand when you lock the dipstick down that when it flares out the rubber, that can get weak overtime and not seal. Will a normal 4L60E dipstick work with my 4L80E trans as far as it being long enough to read properly. It has a stock pan on it. I would assume it would? I dont want to drive the truck with no seal over the dipstick tube. Quote Link to comment Share on other sites More sharing options...

Aldofashow Posted May 31, 2018 Report Share Posted May 31, 2018 I remember Randy aka L8RBRO had a problem with them being different sizes using a 4l60e one in his 4l80 swap and I believe he was running it low on fluid because of it Quote Link to comment Share on other sites More sharing options...
chevybowtie72 Posted June 1, 2018 Report Share Posted June 1, 2018 I wonder if the vent tube on top of the 80e case could be blocked and cause this? Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted June 2, 2018 Author Report Share Posted June 2, 2018 I just got my new dipstick, the part number on it is for the 80 as there is a difference. My old dipstick just happened to break apart as the plastic was old. Quote Link to comment Share on other sites More sharing options...
