Blazer trans fluid check
 

please dont hate on me i thought i would ask a stupid question though. recently my trans fluid has been overfilled, so today i loosened the pan bolts and drained some out (i only drained like half qt maybe less) i have the owners manual since its below freezing here 10* i drove the blazer a couple miles in 3rd. i parked it back in my garage and let it idle about 10 minutes, then i went through every gear with a 3 second pause then back to park. i checked the fluid and it was at the cold mark even though the engine was fully warmed up. i kept adding little by little doing the gears in between. now it is just below the hot mark (below cross-hatched area) i didnt want to add anymore cause i just about put back what i took out. is there something im doing wrong? its shifting like it should no hesitation or slipping, should i just leave it be as it is?

Transmission fluid takes considerably longer to heat up than engine coolant. With 10F ambient temperature, and a good radiator, it might take 30 or more miles of driving after the engine is at operating temperature, for the transmission to reach operating temperature. The factory trans cooler only holds about a cup of fluid and fluid capacity of the transmission is about 13 quarts, so it takes a while to heat up the fluid. Gotta check it in park, engine at idle, vehicle level, fluid at operating temp.

if its on the stick, i wouldnt worry about it too much. but like the Cap't said, its takes a while for all that trans fluid to get hot. try checking it when you get home from work one day. assuming you have at least a 5-10 miles to commute, plus sitting in traffic, so on and so on.

lol i actually only live less then a mile from work, so ill just have to drive up to my local wal-mart and back to warm it up thanks for the info. wow 13 gts i thought it was like 5 or 7 lol

update: i took it for a good drive about 10 miles and back and checked it the level is now in the cross-hatched area but on the lower half

As long as it's in the cross-hatched part of the dipstick, (or between the dots) it'll be fine. If you drop the pan to change the fluid & filter, it will take about 4-5 quarts, but the entire system capacity is ~13 quarts, (torque converter holds almost 6 quarts). Most automatic transmissions built before the early 80's had a drain plug on the converter so you could drain it as well. On the newer ones, you either need to do a complete fluid exchange, change the fluid & filter more often, or change the whole transmission;)

ok ill let it go for now and keep an eye on it. i carry all the fluids the Blazer uses in case of emergency thanks again good little bits of info here

I noticed that my HELM manual for my 1986 Z28 with 700R4 (printed in 1985) states to drain the torque converter, you drill a hole, drain the fluid, and then tap and dye the hole back up. I actually did that!

My FSM for the 1995 Corvette for the similar 4L60E says to just replace the TC.
