shifting prob

supra_91 · 02-02-2007, 06:46 PM

i live in illinois and it is pretty cold here right now and for the past couple of weeks i have noticed that my car won't shift out of first gear when the engine is cold. it finally shifts about 30 secs to a min later but i don't know what is wrong. i have also dropped in gas mileage to getting roughly 200 miles per tank of gas

mine did that a couple months ago. take your car in to a Meineke or somewhere elese and get your transmission system flushed out, and some new tranny fluid put in. after a while it will shift smooth and you shouldnt have a problem.

^^^^ Yes, the first step is to flush the trans. Make sure you take it to a shop that uses the machine to do it. Not just drain and fill, as that will only get 2 1/2 qts. out.

The machine method cleans insides with a mild chemical then removes all the old oil, and reloads with all new oil.

after i get the fluid changed will it effect the bad gas mileage

supra_91 · 02-06-2007, 05:42 PM

what about the gas mileage

mrnickleye · 02-07-2007, 03:41 AM

I seriously doubt it will effect the MPG. That is more an engine running condition relationship.

supra_91 · 02-07-2007, 06:35 PM

the engine runs fine though

Well, if the 'lockup' torque converter is not locking up, it will lower your mpg.

One way to check is to drive the car normally with the OD off. Feel the shifts, 1-2, 2-3, then watch the rpms, and see if they drop 2-300 at around 40mph.

You might even feel it. or hear the engine tone drop a tiny bit.

if you can't tell after trying it a few times, your's may not be locking up.

supra_91 · 02-08-2007, 05:42 PM

okay. i'll try that and see what happens
