How to change the transmission fluid on a 1991 hona civic dx? help!?

i need to change the transmission fluid on my 1991 honda civic dx hatchback with the 4 speed trans and 1.5l motor. help!How to change the transmission fluid on a 1991 hona civic dx? help!?
Although I haven't personally changed the tranny oil on a 1991 honda civic, I have changed tranny oil on multiple cars. On all of these cars, the one common factor, is that some place or another there's a drain plug and a fill plug. Here's the general process:

1) Drive car for approx. 15 minutes to get the oil in the tranny warm.

2) Jack the car up as high as possible that is safe, yet flat.

(be careful, car will be hot)

3) Find the fill plug and remove.

4) Find the drain plug, and catch old fluid.

5) Once fluid is drained, wrap threads with teflon tape and reapply drain plug.

6) From here, figure out a way to get your new tranny fluid into the fill hole. I usually use a long hose and gravity. Others have used suction guns and what not. Continue to fill the tranny until fluid starts to overflow out of the fill hole.

7) Wrap fill plug with teflon and reapply (be careful because most transmissions have an aluminum case)

8) Lower car and test drive, inspect for leaks.



That's basically the gist of it. Good luck.How to change the transmission fluid on a 1991 hona civic dx? help!?
there should be a plug on bottom to drain it,one on the side to fill it, i think that transmission takes motor oil, if it does and you put gear oil in it you'll do damageHow to change the transmission fluid on a 1991 hona civic dx? help!?
On the honda gearboxes auto or manual they have drain plugs on the side of the box, easy way of telling which bolt? turn your wheel and look at the gearbox from the side.

simply get a 3/8 drive rachet and it should fit onto it, look for a bolt with square cut.

refil cap is on top of the box should look for a yellow/black dipstick thats where you fill it and it has a level indicator also.How to change the transmission fluid on a 1991 hona civic dx? help!?
Item 23 is the drain plug which is designed to be removed using a standard 3/8 ratchet wrench.

Item 11 is the dipstick which also serves as the fill hole for new transmission fluid.

The only 4-speed Honda had available for your car was the automatic. Manual transmissions were 5-speeds. Get the OEM service manual for your car from www.helminc.com and follow the directions within to do your tranmission fluid change properly and to Honda specification. While wrapping the drain plug with teflon tape can't hurt as long as none of the material gets into the transmission, Honda drain plugs have a copper or aluminum crush washer that is designed to seal the plug. You should always replace this seal washer anytime you remove the bolt and follow the manual torque specification.



Unless you are doing this in the freezing cold, there is no particular need to warm the fluid to any major degree.



While a manual transmission is filled until fluid comes out the fill hole THAT IS NOT THE CASE WITH AN AUTOMATIC TRANSMISSION! Be sure to fill an automatic until the level reaches the top fill mark on the dipstick with the engine running and the transmission in neutral. You should cycle the transmission through the gear selections to properly distribute the new transmission fluid.



The job is relatively easy. Good luck!
