Doug (6/7/2013) I have a 1991 jeep wrangler renegade, 4.0L, 5 sp manual (AX-15), 75000 miles.
I started to have a vibration when starting out. I thought it was the locking diff. Then I thought it was my clutch. I took it to a specialist he put in a new clutch, pressure plate, T-bearing, slave cyl. & trans. front seal. I still have the same problem. After talking to another jeep owner he said first gear in the trans. does that and it will get worse, but you can have heavy duty parts installed in your trans. and that will take care of my problem. Can you add or confirm this, or tell me what you think?
90 yj owner (4/30/2013) @Jack I. 89 Wrangler: it sounds like your engine is a AMC/jeep 258 or a 4.2 liter. AMC used a ford ignition system on the 258 along with a carter 2 barel. If you would look on the timing chain cover, there should be a AMC logo stamped onto the front of the cover. it is kind of small. there is a chance that your intake manifold would also have the AMC logo cast in to the intake, however after Chrysler bought AMC, it seems like that logo was removed. the following is a on site link to the 258. http://www.jeeptech.com/engine/amc258.html

Jack I. 89 Wrangler (1/23/2012) Sir,
I read your article concerning Jeep Transmissions and issues at http://www.jeeptech.com/convtrans/what.html . I was hoping that you could possible provide a solution to my dilemma.
Here it is:
Situation: I bought a 1989 Jeep Wrangler for $800. Knowing that it needed a slave cylinder replacement I later found that the engine, which also needed some carburetor work is a Chevy 4.20 Liter straight six also had two cylinders which were pushing 80 lbs. PSI The engine is not the original according to the mechanic and when I asked the previous owner he relied on ignorance and stated that it came that way . The transmission according to the mechanic appears to be the original. Everyone is assuming that it is a Ford Engine because it took a Ford distributor cap and worked.
I took it into the shop to have the carburetor adjusted and the transmission looked at because I was having trouble shifting into gear. The clutch pedal, to the hydraulic clutch had to be pushed all the way to the floor in order to shift. I mean all the way to the floor. When I was test driving the Jeep and noticed the seller stated that it was because it was a hydraulic clutch and that it needs to have the slave cylinder replaced.
Problem: Since the repair the Jeep has blown two slave cylinders since repair. Any future replacements would more than likely result in the same result
The mechanic who I believe to be experienced and reputable had to replace the clutch plate because it was worn to the rivets replaced the slave as well. The mechanic is by himself and cannot figure out why this is happening. So far he has stood behind his work but cannot figure out what keeps breaking the slaves.
Another statement from the mechanic was that he had replaced the exact same slave cylinder and transmission master cylinder. All of the parts matched up exactly but after they replaced it they could not get it to go in gear. He extended the master cylinder push rod by a sixteenth of an inch which enabled them to get it into get. Before that after replacing the master and slave cylinder they could not get it to shift into gear at at all. After the extension of “1/16” inch it now blows the slave.
Other stuff and thoughts which may be helpful:
Could the engine which is not the original have an affect on this difference of 1/16-1/32 of an inch?
One forum suggests that the slave is being over extended which appears to be the current situation which sounds good but why wouldn’t it go into gear in the after replacement?
Note: Not trying to confuse the issue but the guy who sold the Jeep stated that he did replace the clutch plate once before which may means to me that he did get into the transmission at least once.
Solution: Looking for suggestions. The mechanic is planning to reduced the plunger rod by 1/32” of an inch to see if that will make a difference but I told him to hold off until we see if anyone else knows what may be going on.
There are some issues identifying just what engine we are dealing with as well but I have some other questions out there. Are there number on the engine as to the make of it?
Moral of this story is. When a needy peddler who you feel sorry for is selling you the best manure around you could probably find some better for the same price.
randy (10/5/2011) hey terry i am in a bad way. my sons 1988 jeep wrangler with the 5 speed tranny lost 5th gear and reverse. i cant find one used and i see the prices are fairly high what i have seen that were sold. we are both back yard mechanic types, would it be fairly easy for us to rebuild this tranny or even replace the gears that are needed? we bought a used tranny the guy said would work, it was a 4 speed with granny low, it didnt work. i am getting a little desperate, and its a nice jeep, he needs wheels bad.
Lonnie J (9/29/2011) hey terry ,I have a 1990 YJ with a 4.2 im told, however the oil pan has a full oil reservoir like the 4.0 and the 4.2 has a different shaped oil reservoir ,do you know if 4.0 and 4.2 oil pans are interchangeable? my engine block id is 909CLZ2 and it is a carburated engine, should i use the new oilpan i purchased for the 4.2 engine? please help me .Thank you for your time
Richard (8/23/2011) Hello Terry,I have a 1979 J10 with the 258 I6 engine. I have the idle problem along the low vacumn.(17) I have tryed everything I know to get the vacumn up except the idle fix you have outline. Are the two problems related? hrwanks
Bob (5/30/2011) Hey Terry, this may amount to a really dumb question but, I've been hearing lately that the 258 (I6) is actually a reworked Ford 300 block... is this true?
tj (3/21/2011) i own a 57 cj5 with f head and need to know if i can pair another type of radiator up with the engine. the oem or replacement model radiator is 450 - 600 bucks and i cant spend that kind of money on a backyard toy. so can i put in a radiator of equal size in and be ok or will it mess up my cooling? please help out. thanks
