Hi

I have a 3.5L 2003 Intrepid and unfortunately the transmission is in the process of dying on me. I found someone local selling a couple of transmissions a 2000 with 100k miles on it and another, off a '99 car he drove for 18 months with 135k miles on it.

The Hayes manual says all Intrepid transmissions are the same, but I'm told the attaching positions are different on 2.7, 3.2 and 3.5 Intrepids and I've seen a link on the internet saying


"Because the superior torque output of the 3.5-liter engine on LH was beyond the 4ITE’s design parameters, a stronger final drive unit was required. This was probably very good for the LH's reputation.

“We put a lot of effort into that,” recalled Howard B. Padgham, powertrain engineer, who also noted that the 42LE’s significant center-section component detail refinements were designed to cope with the added torque, including upgraded clutch packs and barreled axle shafts. The solenoid pack for the 42LE also is integrated into the transaxle for quieter operation.

In the final drive unit, a hypoid ring and pinion gear set delivers drive to the differential and from there to the drive axles, Precise adjustment of the hypoid gears to assure quiet operation is automated."

Does anyone know what the situation is here? Currently I'm driving with 3 gears in a dying car and on balance I'd rather fit a 2.7 transmission and take it easy with my right foot than have a dead car if that isn't completely impossible or just a stupid idea.. Also, there aren't so many 3.5's around so I might have a long wait in finding one. I'm in NS in Canada

Thanks

^^ x2 - ALL the same transmissions.

The difference they are talking about I'm sure is the move into the LX chassis, and talking about what WAS on the LH.

In fact, it is basically the same transmission as the earlier year (1993-1997) Intrepids with either engine - just a few wiring differences and two holes are slightly changed - and the rear cover for the trans mount is different...

If you get lucky, and find a 2.7 trans, you'll have a more responcive and zippier car - your speedo will be slighty off though.

Hi YesImLDS

Thanks very much for the information. The 2.7l has 3.89 gears instead of 3.66 is that referring to the gear ratios? Does it matter so far as putting a 2.7 into a 3.5? Sorry to be rather ignorant on all this.. Also, I was wondering for thoughts on which might be better to buy. 100K miles vs 135K miles that the guy selling it says he has driven for over a years. I'm tempted by the latter. Could be either though I guess. Is there anything that would be a good idea to check for on them when I go and take a look? I'm talking to a guy who seems to have parted out some intrepids over the years, partly for himself I think, and is clearing stuff out from his workshop. He's looking for a reasonable offer. Anyone have any thoughts on what would be a reasonable offer for a transmission? I want to be fair and also not rile him with a lowball offer as there aren't many of these about in rural NS!

Thanks for the help

Andrew

I would say either trans is as good as the other... I'd be partial to the one behind the 2.7, but that is only for the gears. Otherwise, the one with lower miles is what I'd go with if they were both pulled about the same time ago.

Hi cdmccul

thanks very much for the advice. I really appreciate it. I guess the more recently pulled the better.

Hi

does anyone have any thoughts on a reasonable offer? I have pretty much no idea what would be sensible.

Thanks

They are all the same except for the 2.7l has 3.89 gears instead of 3.66 and the 3.2 and 3.5 are made off of the same block just different size cylinders

Except for the wiring, starting in 2002. If he is going to use a 2000 transmission in his 2003, he'll have to swap over the transmission harness from his to the 2000 trans. If he gets an 02+ trans, he's good to go. All engines are the same except the gear ratios as mentioned.

There were more solenoid pack issues 2002+ than before, so a 98-01 is the most reliable transmission, IMO, but low milers are getting scarce. I have never seen anything other than input/output sensors go on a 98-01 tranny, whereas 02+ is a solenoid pack replacement eventually. Less reliable.

Shop around, these trannies can be had cheap. I have gotten them as low as 900 miles for $300-$400....

As Daytrepper said, the 2002+ are starting to show more selonid issues. Consider geting the older tranny and swap the harness. I did not know about the harness requirement.

The harnesses are the same except for the ground circuit for the 02 sensors. There is a ground splice in the 2002+ that is not there in 98-01 (its in the front body harness 98-01)....so if you dont install the newer harness on your car, you will lose the ground splice, and get all kinds of 02 sensor codes, bad gas mileage, angry car..... Ask me how I know. :)

Also, you cannot use a 1998 transmission on 2002+ models. The 1998 has its own harness. It will adapt to other 98-01 models, but 02+, it will be missing the ground splice, and the newer harness cannot be used on it, due to a different solenoid pack plug...specific to earlier 98 models.

From not having those gears all I can say goes off what I have read. People say the car wants to "go" easier. Also I have read like a 1mpg difference between the two.

Hi

thanks all for all the information and particularly the harness info. I'll see if he has the harness to go with it. I think he will because he has 2 complete cars in pieces. Maybe I'll go for $150 and see how it goes.. Any thoughts on what to look for when I go see him? Turn stuff and it grinds to be avoided etc? Check for burnt trans fluid?

Cheers

Andrew

If his is a 2000, you need to use your original 2003 harness on it.

Look for burnt fluid, oil leaks, basically. Best thing to do is drop the pan, see if there are any abnormal metal chunks in it.

ALSO - when you go to install it in your car, fully service it - meaning drop the pan (if you didn't already before buying), and install a new filter. Pull the TC off and empty it as best as possible (be mindful of installing the TC - it has to go past three indexing points, not just two, when re-installing!). Lastly, but just as important, while it is off the car, drop the differential fluid and re-fill with a good high grade gear lube (not sure what is spec'd, but I'd use a high end marine fluid or the full synthetic stuff Ford wants.

Three index points?

...stuff Ford wants?

Sorry, Index is the wrong word - when you slide the TC back on the input shaft, it has to line up to three things - the clutch lockup spline, the main drive spline, and then the pump spline (double D index).

Then the ford fluid - I know that Ford Truck rear ends (mid 90s and up) require a premium synthetic gear lube (had to use it on my moving van I had). I guess I'd use that in our differential cases myself, but I'm sure a standard 80w90 would be fine too.

Hi

thanks very much for the information and advice. I'll try and get the harness for the transmission - no use to its current owner anyway once I take the transmission - and then there's flexibility to switch them if needed.

He's selling a bunch of stuff, front/rear wheel bearings, struts, rotors, calipers, 2 radiators, starters, alternators, tie rods, etc. Plus all the sensors for 2.7 engines. Thinking maybe I should see what else I should pick up that might come in useful. My back rotors are maybe a bit tired.. Any thoughts on what would be a goodie to get? I have a 2.7 as well as a 3.5..
