I have read the wikis on different types of car transmissions aside from the usual manual and automatic, and I am still none the wiser about the types of “in between” transmissions.
As I understand, there are 2 distinct types of this thing in common usage.
Electronic Manual/Clutchless manual transmission. Essentially the same as a manual but moves via electronics.
Discrete automatic/Tiptronic transmission. The same as an automatic except the dirver has control over which gear is selected.
What commonly seen car types have each kind? Because each manufacturer uses different names for their techs, I can’t figure it out. I understand luxury European sports coupes often have the first type, while “sporty” versions of dometic/Japanese compacts will often have the latter. Is this generalization correct?
What are the pros and cons of each type? Is the tiptronic type transmission any real improvement over the usual automatic transmission? I have some experience driving a Tiptronic equiped MB Gelandwagen, but I never actually used the tiptronic function, and I’m not sure if it really serves any useful purpose on that vehicle. Are clutchless manuals a great deal more expensive than all other kinds of transmissions? Otherwise, why don’t we see them more often on cheaper cars?
Your plain-English explanations are apprieciated.
