Ok Plain and simple to the point , i want my van to be stick shift , manual transmission . Take out the automatic and i want to control the shifting. What tranny do i need, can i use an older model tranny or is there a site or place i can buy a new tranny for my van. where do i obtain the parts ?

 

ok its just about impossible. ud need to find pedals, shifter, cables etc from europe. then theres an issue with a trans since 3.3/3.8 engines never came with a manual gearbox but i do know a trans that will work,then theres another problem with the computer because it wont recognize the manual trans and another prob is the speedo wont work and it gets even more complicated. if u want a stick minivan then use a pre1995 those are really easy to convert with a 3.0

 

I think you can make,speedo works. On back of each trany there is a plug for manual speedo's, all you have to modefy trany.

 

no, on these vans speedo comes from the output speed sensor cuz this has a 41te that sensor feeds into the trans computer then across the bus to the pcm and bcm. idk how ud get the one speed sensor needed on the output shaft (old trans type) to communicate with the trans computer when nothing else is going to work. and where are you going to find a manual trans to fit a 3.3 or 3.8 since one was never ever made (although i do have an answer for this) but all the computer stuff is going to make for a lot of problems beside the cel will be on all the time and we all know how much that annoys everyone

 

These vehicles do not have speedometer cables. There is an Output Speed Sensor mounted on the transmission. That sends electronic data to the powertrain control module PCM and the body control module BCM. The PCM uses the speed data to coordinate shifting. The BCM uses the data to drive the speedometer. It's all digital.
Thats right, but this is only on AUTOMATIC TRANY'S, and you want to put manual trany, so the speed sensors useless on manual trany's, they read data and speed, when to shift up or down. And Your right hand and left foot, will replace those speed sensors. That's why called manual trany, which is you listen the engine when to swith the gears. Manual trany don't have and don't need any speed sensors, those sensors only for automatic tranys, to switch gears automaticly instead of you. Get the point? And the manual trany have pluged hole for steel rope, which go in to a speedo. If your state have junk yard you can take one out even with RPM gauge or with out, it's up to you. And you just taped those two plugs from speed sensors, they will be useless on manual tranys. All you have to change brake pedal, and add clutch pedal. It's will be a big job, and you need a nice shop and tools to do that. And one more thing, i thing you will need to do some welding job on van's body to fit manual trany, so you can put shift stick through the floor. Fromy experience, i did one time that but only on mercedes 300 TD. And every thing work excellent except egnition. You have to start van different way, turn egnition key in to run position, and touch two wires to crank the engine, that wire you have to pull from starter to inside. Or find that safety switch under shift stick cover, and try to find the way there, so you can start with the key.

 

i'm well versed in how a manual tranny works and i'm equally versed on the operation of the overdrive transmission both interally and electronically. on overdrive chrysler transmissions the output speed sensor goes to the TCM then from the TCM across the bus to the PCM, BCM, ABS and SRS computers. it is not possible to install a manual trans and use the manual trans speed sensor signal. the od trans output speed sensor is the only sensor for speedo you cant tape them off and have anyway of making the speedo work it just wont work!!. i can state this from first hand experience dealing with a manual minivan conversion on a gen2 van that had an overdrive trans. it was a wiring nightmare to make it work. and besides alex, you tell us what manual trans fits the 3.3 or 3.8 engine? what are you going to use for a flywheel with crank sensor?

 

Ok let's see this way.
Manual trany, don't have even plase for speed sensors, or even TCM plugs, and manula trany don't have those nasty solenoid pack, they juct don't have, because you changing gears instead of solenoid. On all car's, van's, truck,s with manual trany, speedometer works not from speed sensor, they are working manualy turned by steel roap, which go frob trany to manyal speedometer. That means. Manual trany require a manual speedometer. Manual trany have only one single sensor, and it's trany ATF pressure, or temerature.

 

u are not getting it. see this van only came with od trans, the speedo function comes off the trans thru the output speed sensor thru the trans computer across the bus to the pcm, bcm, etc. if u eliminate the trans computer, theres a problem with getting speed signal to the other computers so no speedo. i know this because we did a manual trans conversion on a 1995 minivan 3.0 v-6 that had the od trans. we had to completely rewire the entire engine compartment and replace the pcm. fortunately we could use the manual trans pcm from the donor vehicle we got the trans/clutch assembly from. but the van in question never came with a manual trans so there's no pcm available. oh and you still haven't answered the question. what manual trans would he use behind a 3.3/3.8? and actually manual trans does have a place for a speed sensor on the rh axle shaft but it's a different signal that the od electronic system is unable to recongnize. The last year for minivans to have a cable driven speedo was 1990

 

I'm curious to know if you ever completed this manual transmission conversion. I'd like to do the same thing.
