Hi i own a 94 EX civic coupe with 1.6 SOHC vtec w/5sp i am having problems with transmission the car shifts great and gets good acceloration when the engine is cold and doesnt seem to slip as if the clutch is warn out. When it is hot out and when the engine gets pretty warm the car seems like the clutch is slipping usally around 2-up rpm in pretty much any gear. Its really annoying i have brand new flywheel,clutch,inputshaft bearing,slave cylinder,pressureplate. I searched the forum and the net for answers cant seem to find anything about it. Also this is the 2nd transmission that has done it. could the clutch master cylinder be going bad? Also when the car seems to slip when warm blasting the heat helps. i dont know if the transmission be overheating? I really need help on this. I hope someone here has the answer thanks.

 

your clutch might be greasy. what happend when you try to start out 2,3 gear? does it stall out? do this when it got to operating temp as you stated.

 

alright ill test that out when i go out today ill get the car warmed up really good. also has new seal for tranny shaft inside of it. So what if the car stalls when i try starting off in 2nd or 3rd good or bad if it does?

 

alright i tested it out today the car wouldnt stall when driving off in 2nd or 3rd it would get up to speed really slow also seemed like it was slipping. Anyone Else here at honda-tech have any idea what is going on. hard to keep my post on the first page alot of people keep posting things.

 

Definitely a slipping clutch...

Is your rear main seal bad? Can you see oil dripping from the bottom of the tranny? Oil from the rear main can get onto the clutch and cause it to slip...

 

Should have all new parts. I bought new flywheel,clutch and pressure plate, new throw out bearing, and seals. Also this is the 2nd transmission that has been in my civic that has started to do this. Car doesnt leak any oil what so ever. I really hope i can get this sorted out. What i dont get is by turning on the cars heater and putting it on full blast how does the oil go away by doing that?? Also i think i read somewhere on this forum if the cars engine oil is to hi or low it will mess with the pressure inside the crankcase and can cause problems with the tranny is that true?? Thanks.
