dracon79 Posted May 17, 2008 Share Posted May 17, 2008 Taking off in 1st gear when the truck is cold is jerky no matter how well I shift. Then sometimes when I am coasting slow to a stop sign and I go to put it in first gear it grinds. But it only does this when its cold once she warms up shifts great. I have a 2 wd 5 speed 88 comanche 4.0. She has the ba 10/5. Is this normal for this tranny??? The clutch is pretty new and its not one of those cheap china plastic ones.

Geonovast Posted May 17, 2008 Share Posted May 17, 2008 Clutch may be newer...but how's the slave cylinder/throwout bearing? Sounds like it's not fully disengaging. Link to comment Share on other sites More sharing options...
dracon79 Posted May 17, 2008 Author Share Posted May 17, 2008 I bought the truck from a friend and he won't be back for a few weeks but I thought he said he replaced that but maybe not. When the truck is in nutrel and you push the clutch pedal down and let it back up you can hear a turning noise? Maybe thats it? Link to comment Share on other sites More sharing options...
Pete M Posted May 17, 2008 Share Posted May 17, 2008 Also make sure that the fluid level is at the right height. My old peugeot did all sorts of weird things when the level dropped. Link to comment Share on other sites More sharing options...

When the truck is in nutrel and you push the clutch pedal down and let it back up you can hear a turning noise? Maybe thats it? Is the motor running when you do that? If it is, I'd bet the throwout bearing is grinding. Otherwise you could be pumping air, so ditto on checking the fluid level, and you may try bleeding it.

dracon79 Posted May 17, 2008 Author Share Posted May 17, 2008 yeah the motor is running. I notice it when I am idling like in a fast food line you'll hear this turning noise in neutral. Then when I push the clutch in the noise goes away until I let it back up. So then he didn't put the throwout bearing in correctly or you just think it needs replacement??

It probably wasn't replaced with the clutch. Your slave cylinder and throwout bearing are one piece(internal slave), and they usually go about $100 new, so whoever did the clutch probably didn't bother. And because it's an internal slave, that means the trans has to come out to change it. Link to comment Share on other sites More sharing options...

Mine did the exact same thing but unfortunantly is was right after i had it rebuild :headpop: Come to find out the moron had put in a bad 1st/2nd gear syncro and it was obvious it needed replacement...that sounds like it may be time to pull for a rebuild or upgrade it :chillin: Link to comment Share on other sites More sharing options...
dracon79 Posted May 18, 2008 Author Share Posted May 18, 2008 Yeah thats what I was thinking is it needs to be pulled for a rebuild. I checked the fluids and there full and I am almost certain thats a new throwout bearing ill check though. Thanks for the responses. 8) Link to comment Share on other sites More sharing options...
Imperial21 Posted May 18, 2008 Share Posted May 18, 2008 I had the Puegot trans in my 89 YJ--it got so bad I couldn't hardly get it in and out of gear at a stop sign and it would grind while shifting on the highway. I had the trans rebuilt and new clutch and slave--it was fine for about 3 months then it started grinding again. P.O.S. :mad: tranmissions they are! they are weak due to their clamshell design--anything I ever read about them says they are barely adequate for a stock jeep.--think about it...Puegot built crappy little French cars and bicycles--AMC/Jeep probably used these trannies because they were like a nickle cheaper per unit than an :USAflag: American transmission.

Don't get too quick on the American transmission thing. The Aisin AX-15, which replaced the BA 10/5 in 89 is a Japanese transmission. Awesome tranny, but still not made by Americans.

Well thats one opinion but i happen to like mine...had 190K on it b4 i had to have it rebuild and thats because it had a leak so i had everything replaced/refurb'd...I'm running a 4.0L w/ 7.5" lift on 33's...

Eagle Posted May 18, 2008 Share Posted May 18, 2008 I currently have 274,000 miles on my "crappy" Peugeot tranny. There's nothing wrong with that transmission if you don't abuse it. I had the Puegot trans in my 89 YJ--it got so bad I couldn't hardly get it in and out of gear at a stop sign and it would grind while shifting on the highway. Not being able to get into gear at stop signs is a clutch problem, not a tranny problem. Although if you keep grinding it enough, the clutch problem can [ui]create[/i] a tranny problem ...

I'm glad you are one of the lucky ones! The other thing it used to do was "hop" out of gear on its own--like if you were rolling down the highway and you let off the gas, it would just pop into neutral(usually with a crunch). It would also often whine in neutral with the engine running. And I would hardly say that the transmission was abused-I only owned it for 2 years, it had low miles, saw light offroad use, and wasn't treated like a racecar. :cheers: Link to comment Share on other sites More sharing options...

Thanks for the responses. 8) Please do NOT even consider throwing any money at rebuilding a Peugeot transmission. The parts are insanely expensive and it's a real bear to work on. And then even after all that money, it can self-destruct again in short order. Definitely not worth touching. Link to comment Share on other sites More sharing options...

My old peugeot did all sorts of weird things when the level dropped. Mine does this as well, but otherwise no problems shifting. I checked my fluid level and it's about 1/2 way between the min/max. I'm gonna bring it up to the max line, but why should the fluid level (above min) have anything to do with the "juddering?" Supposedly a new clutch/bearing before I bought it, but we all know what that's worth, right? :brows: Link to comment Share on other sites More sharing options...
Eagle Posted May 18, 2008 Share Posted May 18, 2008 The shuddering on start-up is not the transmission, it's the clutch. I notice you said the clutch is new. Dunno if you replaced the clutch, or if you had a shop do it, or if the previous owner did it or if HE had a shop do it. Whoever did it, I'll bet you a pink lemonade that it wasn't done right. Usually by the time a clutch needs to be replaced, the flywheel has developed some "hot spots." If something isn't done about these, a new clutch will grab better on the areas between the hot spots than it will on the hot spots. The result ==> chattering, or shuddering as you try to engage the clutch in first gear. Traditionally, when replacing a clutch the flywheel was machined to remove the hot spots. HOWEVER -- the XJ/MJ factory service manuals specifically say NOT to do this (but they don't say why). So, my guess is that one of two things happened when your clutch was replaced: either the flywheel was NOT resurfaced, leaving the hot spots and virtually guaranteeing shuddering, or the flywheel was machined even though it should not have been, which can result in the clutch slipping -- which might feel like shuddering.

On mine, the clutch was (allegedly) replaced by the PO himself. Given a few of his other fixes, nothing would surprise me. I figure I'll just live with it until something major needs doing. Then replace the trans with an AX-15. Link to comment Share on other sites More sharing options...
dracon79 Posted May 19, 2008 Author Share Posted May 19, 2008 Well the coworker I bought the truck from replaced the clutch with one of those cheap o china plastic ones twice and realized they don't work. So he bought a expensive metal replacement at a performance shop. I believe he said he replaced the throwout bearing as well I can't remember going to check. But I know he didn't do anything with the flywheel. Funny though once it warms up it shifts great but cold not so good in the first gear. Link to comment Share on other sites More sharing options...
BLHTAZ Posted May 19, 2008 Share Posted May 19, 2008 I replaced the clutch in mine a few months ago. ALL aftermarket clutch kits that I could find came with a release bearing so it should have been replaced unless for some reason he just didn't do it.
