I dont remember there being a 4SPD manual for those years. Unless you are talking about an Automatic, then it is a a 4SPD, however it does have Overdrive. 4th would be the Overdrive gear.
You shouldn't have a problem doing a swap either. All D series trannies will bolt to all D Series motors. Last I checked anyhow.
ahh the 4 speed...
there was a 4 speed manual available only in 88-91. it was in the std hatchback...
other options for the STD included... NO tach.. NO rear wiper... NO passenger side mirror... and a black trim panel on the hatch instead of a red reflective one.
all this is tell tale sign from the outside of a STD.
the 4 speed is a dead giveaway if you didnt know the other options.
parts you need are... a 5 speed trans from an 89-91 car... NOT AN 88
the 88s had a different spline count on the input shaft.
you original axles will fit...from what im told...
personally... i used a set of SI axles with a set of SI spindles. the SI axles and spindles have a different spline count on the outer cv joint. they are the perfered method because if for any reason down the road you want to swap to a B series... you need to use these hubs because the 4 speed axles will not fit the B trans... thus any other axle wont fit the hubs.
you can reuse your clutch as long as it fits the input shaft on the trans... remember about the spline count...
if you happen to pickup an 88 anyway... there are options... you can go on and pickup a flywheel and clutch and pressure plate for an 88... OR and this may sound strange... you can keep your original flywheel and pressure plate.. and change the clutch disc to that of an 86-89 accord.
those are your options. choose wisely...
