99 lumina transmission problems

[jeffcoslacker]

Not up on tranny scan diagnostics. What does fluid volume mean to the scanner, exactly...? I mean what value is it actually reading?

What happens to the fluid temp when it quits working right?

I'd still bet it's blowing off hydro pressure somewhere once warmed up...

I wonder these things as well - the scanner just says "fluid volume" and gives a # -makes it kind of difficult to discuss because you want to say GPM or LPM or something not just "2.4"

It stays the same once it comes to temp - but, I wouldn't be surprised if reaching temp is when the tranny slips... I don't remember the values -may have to check again once I get home

yeah I'm thinking that too - still haven't dropped the pan since I'm working on my blazer and my cougar currently... lumina is the next project

just wanted to point out, i swapped the filter, and it has done ok for a w hile, but its getting worse. there were a lot of filings in the pan when i dropped it as well. I have found a trans i can afford and will be doing the swap this week. any hints?

4t60E ,,,4t65E ,,,transmission pans are very shallow,,,over-fill trans about a quart,,takes trans starving for oil out of the question,,,will not hurt trans......P.S.,,,,scanner will not tell you if hard parts are broken in transmission,,,more than likely foreward clutch seals ka-poot,,,,,if reverse engages ok,,,,then fwd clutch is the problem......

i was always told if you overfill the trans you risk blowing seals... But i do like the idea
