Trans slip and hard shift

[canthus90]

So my trans has been slipping when I accelerate hard and shifts hard from 1st to 2nd..... How long do I got if I baby it? Just started a new job.... I don't think shift kit will fix.... Maybe a filter?

trans is slipping so youve seen a gear ratio error code? people dont drop pans and filters enough nowadays so id bet its time.
that said a partially clogged cat and maf issues can cause both those issues so if the trans doesnt have 120+ but the cat is over 80k id start looking there first.

you can scan for current gear ratio and see if its starting to fall outside of normal, 730 gear ratio error wont trip till its .02 out of range but you can see if its starting to get there.
if the cats clogged pull the narrowband and unplug it, test drive it if the "pep" is back the cats probably clogged, esp at 80+k or if it rattles.
dirty maf will throw off load calcs and cause odd shift firmness/early/late etc

If only I asked you before putting the trans in my truck... I found out I had a clogged cat after spending $2k on a built trans. fml

change your 02 if its over 50k while your at the maint point, if its old and skewed youll pick up mpg/run better

I don't have a o2 sensor Wide ban rear o2 delete

 

[Turbocharged400sbc]

your in open loop? im talking about the upstream OEM narowband O2

 

[canthus90]

I am not sure what your talking about. I have on the headers a wideband innovate and the rear o2 where the cat is suppose to be has been deleted... I always wondered when my brother did this why the wide band wasn't were the back o2 was suppose to be and the front o2 wasn't a o2 i wondered how the engine was getting fed back on how to run

 

[Turbocharged400sbc]

either its in open loop (no oem upstream) or you cant see it

 

[canthus90]

i know there's no o2 sensor the wiring it zip tied up.... but what's a loop

Any codes? Same issue. I had my pressure control solenoid changed but still the same issue. 1-2 it revs up a bit than ban it shifts. After warm it usually goes away. Today I just drove 120 miles and it was perfect. I dropped pan and changed filter, magnet was covered in usual grey metallic. I think my trans is about due.. 136k.
