Shifting hard when transmission gets warm - 1990 Mitsubishi Eclipse

check level of transmission fluid --and may need to have filter and fluid changed

have a pressure test done to check for internal problems . have the clutch pack and bands adjusted

check the clutch operation especially the m/cylinder for failure. The fluid and the master cyl. is probably not disengaging the clutch enough. the rears will not necessarily grate as the synchros are working overtime to spin the gears for alignment because the clutch shaft is still moving under power from the engine.

Yes also could be low on fluid have you changed fluid and filter since you have owned it?

It sounds to me like the transmission is starting to fail. As the clutches inside the transmission wear the clutch pack gains additional clearance. Your pressures in the transmission will be higher with cold oil so it has a tendency to build a bit of extra pressure, but it's also slower in flowing through the transmission. This results in a harder hitting first gear. As the transmission warms up, it will reduce the viscosity of the oil and work fine. Cold weather kills automatic transmissions. Let it warm up before driving it or it won't last long. It will require an overhaul soon.

A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.

Some possibilties, not all!

First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.

Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,

i gather its an auto transmission ,which mean your loosing oil pressure from the convertor inside the tranny housing.

hi you need the seals replacing in the box when they are cold the become hard as they warm up they start to do what there are suppose to yates210456
