Gearbox woes - 1st/2nd gears on opposite side :/
Hi guys, really strange one, after fitting gear lever to gearbox (only needed to purchase 1 linkage rod) seem to have a problem of 1st & 2nd gears being on the opposite end of box, so where 5th and reverse should be! 3rd & 4th are where they should be. Played around the linkages and can't seem to correct, my mechanic seems to think it's the wrong gearbox.
It's an 87 300gd, how do I find out if the gearbox in there is original one? Also what would cause this problem?
Go to MB get a spares print off associated rods and check against this? Alternatively post your gearbox type and number up here and someone will know.
From underneath in neutral do all the levers( hockey stick type ) line up? Do rods look right?
As Jason said do all rods line up at gearstick end in neutral. Even if they do it seems like you have connected a rod to the wrong lever
As far as i know all gearboxes of this type use rods in the same order
If the wrong selector linkage rod is fitted to the wrong lever at gearstick by error this will produce the problem you have
Swap rods over and im sure all will be fine
With chassis number in hand get your local dealer to do a data card printed off for you and on that should be the factory spec of gearbox fitted. Simply check against with what you have. You will need to read off your gearbox number stamped on the gear box - somewhere.
Was the gear lever a new replacement or secondhand? It could be this is wrong or not off a G-Wagen? I do not know, just conjecturing.
In replacing the gear lever, the selector rods are not disturbed as the whole renewal is top side.
Whilst drafting this thread; I have checked the layout of the gear lever but my records only cover the four speed layout and if this is a pattern of help then looking from the rear of the vehicle, forwards at the selector rods.
Looking from the left side (near-side) the first selector is for the reverse gear (on the five speed gearbox, reverse and fifth are the same selector rod). The next selector rod in, is for the first and second gear, then the next selector rod in is for the third and fourth gears.
Hope that is of some help.
Ok thanks I'll try get pics of underside but my guy is adamant on the linkages being fitted correctly he followed the diagrams. He seems to think although the box is 5 speed the actual gear lever and the box may from a 4 speed, the g was clearly tampered with when I purchased it as it didn't have gear lever connected at all.
I have 5 speed boxes available with the associated full gear linkage/gear selector.
Send me a pm with your number and I'm sure we can get you sorted, if it is a 4 speed box it needs to go in the nearest bin asap.
Messaged. it's a 5 speed box, but I believe the actual lever/ box is incorrect. I have to lift the lever to get to 5th gear and reverse which are located top and bottom left.
On a 5 speed manual 460 reverse is below 5th knock the lever right to engage
On say a 5 speed 190e it is lift up and is left of 1st. 1/2/3/4/5 are all in the same place.
I am told a 5 speed 190e box will fit some engines fitted to 460 G's
Sounds like someone has fitted a proper steel/van MB 5 speed instead of the original chocolate Getrag or maybe the 190e?
On an original 5 speed Getrag manual 460 reverse is below 5th knock the lever right to engage
On say a 5 speed 190e it is lift up and is left of 1st. 1/2/3/4/5 are all in the same place.??
On a 5 speed van/granny MB box 1st is on the bottom left (i.e. dogleg) and reverse is opposite it (but a little to left with detent). 4th and 5th are on the same plane at right. That needs a Cosworth 190 Gear mechanism (I fitted this combination after chocolate Getrag died..). I did do a post on it but it needs a shortened prop to gearbox and I cut and shut my linkage rods to make them work. See here; http://www.pointedthree.com/disc/forums/showthread.php?tid=18318&start=1
This link is now dead but it did cover this "Fitting a 190 2.6 Gearbox to a 280GE http://www.gwagen.de/html/english/gearbox.html
So you may yet have a better gearbox...easy thing would be to read the part number off the gearbox.
G 460 Getrag =717.439 190 2.6 car=717.432 Van box = 711.113
Hi guys had some issues with logging in hence late reply.
My mechanic has sent pics of the underside, these don't mean much to me but would love if someone can shed any light on whether the gearbox linkages set up seems correct.
To remind you of problem 1st and 2nd gear are hard right up and down and 5th and reverse are on the left side of the box ( as you are sat in car)
