Linear Solenoid questions
Ok guys I have a 98 Civic EX auto that was driving fine until last week when out of the blue the trans decides its time to make all upshifts and down shifts neck snapping. The trans shifts and down shifts extremely hard now. I have removed the solenoid on top of the trans as well on the passenger side closer to the bottom of the trans, cleaned the screens and tested with 12v. All four click like they are working. I removed the linear solenoid last night cleaned it and tested with a multimeter. I'm getting around 8.1ohms on the two pins however when I try connecting to 12v and grounding the other wire to the solenoid like I did to the above solenoids I get nothing. No noise, no clicking etc. My question is before I go spend $100-$150 should I be hearing a noise from the linear solenoid? If not any ideas what would cause the hard shifts/downshifts? I've already flushed the trans also.
Thanks!
Thanks!

This also may apply:
There is a known problem with automatics in civics between 96-2000. It could be the linear solenoid, which is different then the solenoid shown in the other post. Is the check engine light on or the D4 trans position indicator flashing? How many miles on the car? Civic autos are usually good to 150k+. I have read about the need to shift manually when the linear solenoid goes bad...

Re: Linear Solenoid questions
I'm going to move this thread to the Transmission Subforum as it will probably get much better response there. The tranny gurus tend to watch in there more than the 92-00 forum.
I must Say Bently Coop has done a fine job in replying though. Hope you get some more solid feedback in the tranny forum.

Re: Linear Solenoid questions
Honda ATF. Yeah I seen this but it doesn't say if the solenoid should click or not. I have another working civic I guess I could try and swap them to see if that helps

Re: Linear Solenoid questions
There was a TSB for those linear solenoids going bad, but I have yet to see a case where there was actually anything wrong with it. 99 times out 100 the trans is toast.

Re: Linear Solenoid questions
Linear solenoid is a wasted repair part. Valve body screens and the pressure pipe screens get clogged. Disassemble and fix the clogged passages.
This was Honda's way of not rebuilding the units. The B7XA, B7TA, etc also suffer the same caliber of issues. Converter burn-up, and clogged passages/stuck CPC valves. The civic units also have problems with the end cover drum cracking. While it would be reasonable for the linear solenoid to require replacement due to non-movement, its the clutch material that causes it.
Rebuild kit, replace the end cover drum if its cracked, and free the valves/replace the end plugs. Drilling a pilot from line pressure to converter primary charge will help prevent converter overheating. Today though you can just but a shift kit for it.
