Hello! So im currently having issues with my auto trans, im looking for replacements but its near impossible to find any auto trans online or in person, are theyre any other known auto trans that will fit the d15b2? Maybe from the same year integra? Any help is appreciated thanks in advance! last resort is manual swap but this is my daily so i cant really have it be down for a long time

 

Careful when you say same year Integra - the first gen 88-89 had the D16A1, but 90-93 Integra had the B-series. I would assume that the D15 and D16A1 share the same bolt pattern "all D series are the same" but I would want to verify that before buying anything. The D16A1 was an oddball D engine, so the trans could be different as well.

What's going on with your automatic trans? Maybe you can rebuild it?

 

Thanks for the reply! But whats going on currently is that when im slowing down and it downshifts from 2nd to 1st it jerks forward.

 

If that's all it is, I'd change the fluid and filter (if it has one). I took a quick look at some older HT threads, new fluid (and maybe an additive) seems to ease the shifting. After that people recommend adjusting the throttle control cable, on the trans of course. Totally forgot these auto trans are cable operated too hah.

My Haynes manual (84-91 Civics) goes over adjusting the throttle cable for the trans. Make sure bracket is adjusted correctly, apply vacuum to "the dashpot", loosen/tighten the securing nuts and ensure cable freeplay is to specifcation:
It states that the throttle cable deflection should be within 3/16 inch to 3/8 inch (4-10mm). It does not specify whether that is for the actual throttle body, transmission, or - what I assume - both.
I don't remember if I have a vacuum tool here so I'd probably give it a shot without it first lol.

 

Man you are a life saver i can not thank you enough i adjusted the cable that goes to the throttle from the trans and it is perfect now!!! much love <33
