D-series L3 Cable Transmission question
Will the ring & pinon gear of a 88-91 Si D-series L3 Cable Transmission (with a Final Drive of 4.2500) directly bolt into a L3 Cable Transmission from 88-91 HF (Final Drive of 3.8800)?

Re: D-series L3 Cable Transmission question
im not too sure but if i think the hf transmissions use a "small bearing" case unlike the si's. i did read somewhere that the 88 si transmission is a small bearing but i could be wrong.

Re: D-series L3 Cable Transmission question
yes, the countershaft and ring gear will swap right in - you need to unbolt the ring gears from the differential carriers and swap the Si ring gear onto the HF carrier - ring gear bolts are left hand thread

Re: D-series L3 Cable Transmission question
Ahhh - so I can't just swap carriers... Cool, Thanks for the info!
I had the idea (probably not original); 1st, 2nd, and 3rd are numerically closer to each other in the HF than in the Si. As I mentioned above, the Si has a deeper final drive. So if I could take gears from one and stuff into the other... It should make a quick little tranny combo.
Thanks Again!

1st = 3.25
2nd = 1.944
3rd = 1.343
4th = 1.033
5th = 0.878
Final Drive = 3.888

Re: D-series L3 Cable Transmission question
First; I need to correct myself from above... "1st, 2nd, and 3rd are numerically closer" should read "2nd, 3rd and 4th are numerically closer".
And. Maybe I got some bad info... Check my numbers.
88-91 HF L3
3.2500 - 1st
1.6500 - 2nd
1.0330 - 3rd
0.8230 - 4th
0.6940 - 5th
3.8800 - Final Drive
88-91 Si L3
3.2500 - 1st
1.8940 - 2nd
1.2590 - 3rd
0.9370 - 4th
0.7710 - 5th
4.2500 - Final Drive
So, looking at both 2nd gears the HF is closer to 1 than the Si. Also the stretch between 2dn and 3rd in the HF is only 0.617. The Si is 0.635. Same is true for the 3rd / 4th change. Smaller number = closer distance, right? True between 1st an 2nd is a longer reach - But I’m not drag racing. I'm more of a time attack kind of guy, where I spend very little time in 1st. my life in between 2nd, 3rd, and sometimes 4th. Now, combined with the deeper final of the Si, should keep the R's in the power band. Those are my thoughts - at least.

Re: D-series L3 Cable Transmission question
I just want to verify - the countershafts are different and I cannot swap only the ring gear. Right?
