Or did they miscalculated horribly?
Did they still make the "H.O." after 99? I thought that was discontinued prior I could use an extra 25 ponies in my TJ

"Also, MJ's through 90-92 are equipped with a heigh sensing proportioning valve that is used to change the bias of the brakes if the bed had a load in it."

My 88 eliminator has this valve...

I just picked up a 87 Comanche, it also has the height proportioning valve. Also just read the tag on my front axle and it reads 3 54 46-13 indicating my 2.5L / 5 spd has 3.54 gears which I don't see on the list, So either my axles have been swapped or ? . Anyway the information is great, thanks!

jpringlemn, some of the Comanches came with 3.54 gears, so I would say your axles are original.

Jeep 4.0L info

The difference between the 4.0L and the 4.0L H.O. is a combination of cylinder head design, fuel injection type(from throttle body - renix- to Multi Point Injection), and computer tuning.

The 4.0L (standard) ended production in 1991, when the 4.0L H.O. came out. Though the "high output" was later dropped, it is still the high output version.

As time went on, it's power increased from 180 to 190hp, in all but the wranglers. Due to its more restrictive exhaust the YJ and TJ, took more fine tuning over the years to develop 190 hp. I don't remember the years that everything took place, but you can probably find it online.

As far as I know, no 4.0s came from the factory with more than 195hp. I spoke with a jeep engineer who mentioned in some of their test, they had the 4.0L getting 300 hp by playing with computer tuning, but the MPG suffered greatly.

Sometime around the 99 year model the 4.0 came with a "dual plane" intake, instead of the traditional straight runner. This occured when coil packs replaced the distributor. I believe this combination yielded more torque in the grand cherokee.

Thanks for the info...sure wish I could computer tune mine to get twice the horsepower; where I live, I can spare the gas mileage

But I'm gonna see if I can find an area on the first page for this info. Again, thanks

based on the first post, im wondering if my guesses are correct.

I have an 89 Eliminator 2wd. It has a 4 liter and a 5 speed.

Am I correct to assume I have .307 gearing and an AX15?

Also, whats the scoop on the Peugot trannies that were used? What applications did those end up in?

All the 4.0L I-6 engines are MPI (Multi Port Injection). The only engine that is TBI (Throttle Body Injection) is the 2.5L I-4.

I think your assumption would be correct, but I can't guarentee it. I don't think it would have an AX-5; the AX-15 I'm pretty sure of. As for the gearing, that's what I can't fully guarentee, but most are .307.

As for the Peugot trannies, they mostly ended up in the 86' models I think. If any ended up in 87', it must've had to be the early part of the year in the bare-bone models.

Mine is an 89 and it's got it. They switched to the AX15 sometime late in 1989.

The Peugeot transmission was not used in 1986. The AX-4 (4 speed) and AX-5 (5 speed) are Aisin transmissions. The 2.8L GM V6 which was only offered in the 1986 Comanche was not available with a 4 speed manual tranmission. It was only available with the 3 speed automatic and the 5 speed manual. The 4 speed manual was only available with the 2.5L I-4. Also the 4.0L I-6 was not available until 1987. It replaced the 2.8L GM V6. The 4.0L was only application for the Peugeot BA-10/5 (5 speed) transmission. The Peugeot BA-10/5 was used until 03/09/89. The AX-15 was used from 03/03/89 which means there were 7 days when they built the Comanche with either transmission.
