My honda civic 98 hx m4va transmition type,the trans drives fine exept when gearing up I can't feel when shifting and rpms goes up and down,I replace the transmition and still doing the same, also when shift into drive or reverse I push the gas and take a few seconds to start drive...but doesn't slip

Time for the dealer to take a look. You need special skill and special tools to diagnose this not to mention years of experience with electronic engine control systems.

check your shift linkages if the bushing is worn out you may have problems shifting or it could be a bad transmission

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.

If it is an Automatic, there is only one cable that goes to the transmission. If it is a manual, there should be two. You will have to disconnect the cable from under the hood, and see if the levers are loose there. If they are, it might be as simple as tightening them back down. If not, the trans may need a rebuild.

have you taken it to transmission shop? if not there are clutch packs in the trans that can cause that problem and might need to be replaced also your car is equipped with a transmission computer and may have problem there have it read with scanner from local parts store or shop find out whats wrong for sure its worth the money to know for sure!

sounds like ur sencanizers r broke

you need to replace clutch pack for that gear can be ordered seperately from parts store or dealer if you want to save money call peach street auto recycling at 1800-365-2341 for a warrantied used one! also might be time for change trans filter and fluid filter could be slightly clogged but I lean towards clutch pack I replace these alot on Hondas

ck the coolant level if this is ok then its the idle air control valve

what are you doing at the time? just normal driving or stepping on it? email me with more info or questions at [email protected]

sounds like either a faulty igniter or air/fuel sensor
