2013 Chevy Silverado LT 1500 Half Cab - Transmission issue trouble shooting (No Engine Light)
bought this vehicle recently and after about 3 months of use and 6 months of owning it suddenly has been giving me issues with what i believe to be the transmission. the vehicle revs and acts normally in neutral and park so i believe it too be a transmission problem. there is no check engine light and the temperature is only slightly higher them normal.
The vehicle is spiking in RPM before shifting into gear, what to my understand is the transmission slipping, like the torque converter doesn't have fluid, Ive bought fluid and gave it fluid when i had an issue and found my transmission fluid slightly low. however after checking my transmission fluid (after the problem began/While engine was hot) i found the transmission fluid red a lot higher then the hash marks for a hot transmission meanwhile a weak earlier after running it for approximately thirty minutes (what i would assume would be a hot transmission) it read in the cold. i did not check the temperature for the low reading however the high reading was 225.
i'm assuming that their is plenty of tranny fluid, what i believe is that the torque converter is bad and needs replacing.
to clarify the problem
The RPM is running high and spikes when going from first to second gear before falling. it is not shifting super smooth and it wants to spike in RPM without it being given more gas.
Assuming fluid level is OK you really need to have the transmission diagnosed by an expert with a professional-grade scan tool that can read transmission codes and data. It sounds more likely to be worn bands or clutches than the torque converter. (Is fluid burnt or gritty?)
That is my next course of action, the clutch was the next thing because i could smell something very occasionally leading up to this issue and from my limited understanding. however it doesn't seem to be overheating.
fluid seems fine, what Ive taken of the dip stick appears to be quite clean, not dark and nothing foreign
The source of the problem should show up in transmission data. Unfortunately that takes an expensive scan tool to see.
