Update.
upon closer look and good flashlight it was fine sparkles. It was dirty and it seemed like my filter was almost sucked in I guess is the only way I can put it. Looked and felt weird. Cleaned everything reinstalled new filter and fluid and it seems to shift fine now. I just did a service about 20 000 ago. Going to probably still need a rebuild soon though I’m guessing

One other question
im having a suspicion maybe my pcm may be going bad. I changed all my fluids and it started shifting. But only for my hydra tuner if I switch tuners it doesn’t shift. I changed because I was having a bucking issue under high Acceleration. Don’t have my pcm code on the device so I went with my my previous tuner was and I think it’s wrong. But I have also been getting a KAM code and now a neutral safety switch code and a few more I can’t remember. Do you guys an opinion possiy

you really need to Verify the PCM Code, or everything you try to do, is headed downhill.

the code can be found on the module behind the Radio, down a bit, and slightly to the left. that will be a 4 digit code, and the Hydra Tuner will translate that for you

ForScan can get it also. IIRC....

EDIT:

I see you have the Hydra.
hook it up to the Windows Laptop, and look at the Code Settings, it will show you what Code name you are using now...

hopefully, that is the same as what the PCM has in it.

I finally found something on performance coral website it led me to a site I entered my vin and it told me it is supposed to be a xle4. I don’t know if that’s what the previous owner installed since it’s a remanned PCM this is the only writing on the pcm

It does
say f5sb but in the hydra tune library that code didn’t come up I’m sending this one in to be tested and reflashed if it’s able to so I can use my Hyde how it’s supposed to be used

did you read the Code on the module behind the radio, down a bit, and to the left?

Hydra program in the Laptop can translate that into the name you need to use.
