What is the 4 + 3 manual transmission in some model corvette years ?!?!?!?! i never heard anything of that !
What year are you thinking about? Ive never heard about the 4+3
Is that something like, where each seperate gear has an overdrive. Like 1, 1od, 2, 2od, etc.
Just like Cougrrr302 said, except there was no 1od: It's a four speed tranny with an additional overdrive unit tacked on. Overdrive is accessible in 2nd, 3rd and 4th gears, hence the "4+3"
ive heard of them and im pretty sure my friend has this trans in his 82 vette if that helps narrow down your search.
Another intresting fact.. No Corvette ever came with a 5 speed. either 4 speed, 4 + 3, then 6
You could sorta make one for yourself if you got a 4-speed plus a gear splitter. (of course, it would then be a 4+4) I've thought about that possibility. I've found a few different gear splitters.. even one that mounted between the bellhousing and the main transmission on some truck 4-speeds. There was one truck 4-speed I found.. T18 or 19, I think.. that had some pretty sick first-gear ratios available.. (we're talking like 6:1) but I have no idea if they'd even fit in one of these, with or without serious modifications.
I was really hot to use a splitter for awhile.. now I have other possible plans. They're pretty expensive little units. ($2000-3000, if I recall)
that they're expensive as heck is one thing, but a t-19 would not fit under a 'Bird without some big ole dents in the tunnel...
They mainly came under 4x4 trucks and stuff.
I guess they put the mazda 5 speed that the f-150 got in the '90s, but I don't see how it woulda fit...??
I have a t-18 I think in my dads van,(just got rid of a extra one too) And it looks smaller then a t-5. Its definetly smaller then an AOD.
