I have a 1998 chevy blazer with 130000 miles, a while back (15000 miles ago)I changed my trans pan fluid and filter due to the same problem, and this fixed the problem until now, I was reading the earlier entries, do you think I should replace my converter fluid, will this help the problem, or should I replace the Tcc solenoid. The problem occurs between 25-35 mph when it shifts into second, it gets all gutless acting like a slip, then when it does shift, it shifts fairly hard, 10 times harder than it used to even under hard acceleration, and if i stay in the 30-45 mph range it acts like it wants to upshift into third creating a lack of power problem cause the rpms are too low. Does anyone have any Idea what this could possibly be? Thank you Jared |

Replying to: rhtrans (Feb 04, 2008 6:56 pm) But wind it up in first or second gear and around 4500rpm ... Goes complete slip, as in shifted to neutral. Let off the gas, transmission hooks up and all is normal. The one clue I see is the fluid looks like it foamed. Now, I just bought this car, and it does have a 12/12K warranty that covers the tranny if it is toast. But someone has recently service the fluid, and I am thinking: 1. Wrong fluid. Should be Dexron III, but no way of knowing what is in there. 2. Wrong filter/dirty filter 3. (and I am leaning toward this one) Whoever put the filter in didn't notice the o-ring missing. Under high suction this would really pick up air and foam the fluid. Opinions are welcome! Jim Forgot to add, records show regular service, Blazer has 62K miles.

Replying to: jlflemmons (Feb 05, 2008 8:49 pm) Dealer checked for codes, nothing there. So, dumped the programming from the PCM and did a fresh upload with all the current updates from GM. Shifting is much crisper, but the engine went into rev limit just as the tranny shifts out of first under WOT. I think I will go ahead and do the fluid and filter change this weekend and go from there. The dealer checked the extended warranty and says if the tranny needs a rebuild, it is covered. Nice to have that safety net!
