ekulrenlig Posted February 17, 2007 Posted February 17, 2007 Will a T-4/T-5 transmission match up to the 2.5L to replace my AX-5? Is the T-4/T-5 a better tranny than the AX-4/AX-5? Also, will an AX-15 replace the BA10/5?
DirtyComanche Posted February 17, 2007 Posted February 17, 2007 T4s and T5s suck. But, yeah, one with the correct bellhousing/input/output will replace an AX-4 or AX-5 - AFAIK. And an AX-15 can replace the BA10/5 - there's some tricks to it.
ekulrenlig Posted February 17, 2007 Author Posted February 17, 2007 Why do the T-4/T-5's suck? Even as a daily driver, no rock climbing or such? So the AX-15 won't bolt right in place of a BA10/5?
jeepthing07 Posted February 17, 2007 Posted February 17, 2007 T4/5 is slightly stronger than the AX5. I thought about getting one from a 2.8 S10 and useing it in my comanche but ended up with a free AX5. A T4/5 should bolt to a 2.5 i don't know what spline the t-case is. i don't know where the shifter would come though the floor compared to a AX5 and i don't know what it would do to the length of the driveshafts. to put a AX15 in you would need a bellhousing from a dodge dakota with a 2.5 and the AX15 and i think they are hard to find.
87manche Posted February 17, 2007 Posted February 17, 2007 regarding the AX-15, novak or advance is making an adapter, it's a pricey piece of machined metal, but it exists, and they could help you with the rest of the swap. Jeff posted up a link/photo of it a week or so ago somewhere around here.
Pete M Posted February 22, 2007 Posted February 22, 2007 Technically, he asked if an AX-15 will replace a Peugeot (ba-10/5) and the answer is yes, sorta. The T-case from the Peugeot will be 21 spline and the AX-15 will be 23 spline so you'll need a matching t-case too. Run a quick search for the swap and it should come up with plenty of other little details I'm forgetting.
Eagle Posted February 23, 2007 Posted February 23, 2007 When the Cherokee was first introduced in 1984, AMC/Jeep couldn't get enough AX5s to keep up production so they were using AX5s and T5s interchangeably. My friend in Greece has an original 1984 XJ 2.5L (built in the U.S. and imported to Greece by the previous owner) with a T5.
carnuck Posted February 23, 2007 Posted February 23, 2007 You can put an AX-15 behind the 2.5L with the bell from a 2.5L 4 cyl Dodge Dakota with AX15. You can also use any trans behind a Chev 2.8L (like used in S10s) but you'll need to make a hole for the CPS if you're not carbureted.
ekulrenlig Posted February 23, 2007 Author Posted February 23, 2007 If I got the bell housing from the dakota, an AX-15 will bolt right in? Are any other modifications needed for that? Any trans behind a Chev 2.8L will work? Do you know any model numbers? Would this bolt right in without any modifications, except the CPS hole? Which would be the best way to go, the dakota bellhousing with AX-15, or the Chev trans, or just stick with an AX-5?
JeepcoMJ Posted February 24, 2007 Posted February 24, 2007 You can put an AX-15 behind the 2.5L with the bell from a 2.5L 4 cyl Dodge Dakota with AX15. You can also use any trans behind a Chev 2.8L (like used in S10s) but you'll need to make a hole for the CPS if you're not carbureted. I thought that the dakota 4 cylinder was a chrysler motor? is that still the same bellhousing as the 2.8? I was told no since the 2.8 is a 60 degree motor/bellhousing system, the dakota ax15 would not work. can you clarify that, I'm SICK of my ax-5 being a POS! :headpop:

I have always understood that the Dakota 2.5L was the Jeep engine, but now that I'm looking for something to document it, I'm not finding anything. I'll keep looking. That aside, what possible difference could the fact the 2.8L is a 60-degree V8 make? The transmission doesn't know or care how many cylinders are in fron of it or if they are in-line, 60-degree, 90-degree, or 180-degree.
carnuck Posted February 24, 2007 Posted February 24, 2007 He just meant the bell pattern. The 2.4 is a Chrysler motor. The 2.5 is the Jeep engine. The AX15 bell from a Dakota is the holy grail for TJ owners right now so they are getting harder to find.

The transmission doesn't know or care how many cylinders are in fron of it or if they are in-line, 60-degree, 90-degree, or 180-degree. the 2.8 is a 6 cylinder. the difference between 60 and 90 degree is the bellhousing. the 60 degree has a specific bellhousing, while the 90 degrees have another. the 2.5 from 87 and 86 has the 60 degree type gm bellhousing, while I am not sure of which the dakota 2.5 has. and the ax5 specifically isn't a POS. however, mine has a bad 2nd gear syncro. i can drive it just fine, but if I pull it i'm putting a better tranny in so i can transfer the power from my 220 horse 3.8 buick to the rear axles and NOT worry about breaking anything.

The AX15 bell from a Dakota is the holy grail for TJ owners right now so they are getting harder to find. What 2.4L engine? From Wikipedia's entry on the Dakota: Engines * 1987-1988 - 2.2 L K I4, SOHC, 96 hp (72 kW) * 1987-1991 - 3.9 L LA V6, 125 hp (93 kW) * 1989-1995 - 2.5 L K I4, 99 hp (74 kW) * 1991 - 5.2 L LA V8, 170 hp (127 kW) * 1992-1993 - 3.9 L Magnum V6, 180 hp (134 kW) * 1991-1993 - 5.2 L Magnum V8, 230 hp (172 kW) * 1994-1996 - 3.9 L Magnum V6, 175 hp (131 kW) * 1994-1996 - 5.2 L Magnum V8, 220 hp (164 kW) * 1996 - 2.5 L AMC I4, 120 hp (90 kW) 2002 was the final year for the four-cylinder engine in the Dakota, as Chrysler was ending production of the former AMC design. Most buyers ordered the V6 or V8 engines, which were considerably more powerful and, in the case of the V6, which was made standard for 2003, nearly as fuel-efficient with a manual transmission.
carnuck Posted February 26, 2007 Posted February 26, 2007 Someone showed me a 4 cyl in a Dakota that had 2.4L on the emission tag. Didn't look like the Jeep motor so I assumed it was the same motor used in Caravans.

IDK man, i just wanna know if i CAN substitute a dakota ax15 for my ax5. second gear is starting to die real bad on it...

Wait, google search pirate 4x4 by typing 'www.pirate4x4.com: 2.5L AX-5 AX-15 swap' or such and you'll find a massive thread on how they did it. Somebody (novak, AA?) now makes the bellhousing to do it without visiting the junkyard. And you should be able to used the dakota AX-15 - it will have the same style of output (spline count might vary) and stud pattern for a 6-stud aluminum NP tcase - ie; 90% of them, including jeep applications.
ekulrenlig Posted February 26, 2007 Author Posted February 26, 2007 So, a tranny from a 2.8L chevy engine will replace an AX-5?? What modifications are needed? Also, what range of years for wranglers with the 2.5L have a swapable tranny for my AX-5 (87 MJ)?
JeepcoMJ Posted February 26, 2007 Posted February 26, 2007 So, a tranny from a 2.8L chevy engine will replace an AX-5??What modifications are needed? Also, what range of years for wranglers with the 2.5L have a swapable tranny for my AX-5 (87 MJ)? no mods to fit a 2.8 tranny, just use your clutch and clutch accessories from the 2.5 if that's the engine you have. or the torque converter/flex plate.
ekulrenlig Posted February 27, 2007 Author Posted February 27, 2007 Yes, I have the 2.5L engine. Do you know what model trannys for the 2.8L chevy engine would work? From what years and makes can I find this tranny in chevys? Is this 2.8L the same 2.8L used in early 80's XJ/MJ?
Pete M Posted February 27, 2007 Posted February 27, 2007 The Jeep 2.5L will need the CPS in order to run. Did Chevy ever use the CPS on the bellhousing like Jeep?
carnuck Posted February 27, 2007 Posted February 27, 2007 It doesn't take much to make the hole for the CPS. I use the engine plate as a template with full size bolts through the biggest holes to hold it in place against the new trans. I've done a couple Jeep 727s so far. (putting EFI into my buddy's '80 Wagoneer with 258)
JeepcoMJ Posted February 27, 2007 Posted February 27, 2007 The Jeep 2.5L will need the CPS in order to run. Did Chevy ever use the CPS on the bellhousing like Jeep? the CPS slot is there. the 2.8 just doesn't use it. any chevy 5 speed 2.8 will have it. I'm not certain about the autos, but i'm sure that it's the same system. I would presume so though.
carnuck Posted February 27, 2007 Posted February 27, 2007 One from an S10 won't have the CPS hole. You might even find an S10 4x4 Blazer ('86 vintage) with 2.8L and 700R4 trans (had a customer with one today) that has a NP231C attached.
