I've been mulling this for months. my transmission specifically says Lt-3 only. which made me pucker and not spring for the lt-5.

do you have any info on one over the other and why? I've seen that lt-5 is for 235 and lt-3 in my 228.
I believe there was discussion in the forums that the LT3 was originally for the M235 6MT as well and then it was changed to the LT5. My thoughts are if it was changed from 3-5 for that BMW manual of the same era then why not.
