Or parts as in a component update to a vehicle? Very vague question. I'll answer a couple though.
Or how about #6? Because that answer will vary depending on what model of trans you are diagnosing. On a Chrysler (Dodge) trans for example, (lets use the 42RE-48RE) from the factory the transmission does not circulate any oil into the T/C (or really anywhere for that matter) when the vehicle is in park, but it does in neutral (and all other manual valve positions). So, it isn't uncommon at all to have a drain back issue after sitting a few days. Once it starts, the vehicle won't move right away when moved to drive or reverse. Rather than go tearing into the trans to fix something that Chrysler says there is no fix for, I'd just file off the corner of the land on the manual valve so that the pump lubes in park, and it will fix the issue. It only takes a few seconds of run time to fill the converter back up, and you no longer have the hesitation. I file every valve on ever Dodge trans I do so that it cures the issue. Very common issue on a Chrysler.
Now, if it's a Chevrolet trans, different story. If it is losing fluid in the converter, then it could be a number of things from a leaking front seal, to a blown o-ring on the input shaft, to a weak pump to an air leak on the suction side of the pump, or even low fluid.
And I may not have even understood the question.... Like I said, some are vague.
Question 4: Seriously? This thread is about the overhaul of an automatic, and you are asking what the trans cooler lines are? I mean, I'm assuming you just pulled the questions at random, but you could have gotten some more difficult ones.
Question 14: Now see, there is a good question. It wasn't vague, and it's a reasonable one, albeit a pretty basic knowledge question, but I'll answer it with a short answer. A 3rd differential in the transfer case. That good enough?
Question 11: I'm going to look for vacuum leaks first. Then I'm going to check the MAF against the O2 and see how they compare, then check fuel pressure. O2 codes are usually just indicative of another issue.
No, I think you are the only one that wants to know my thoughts on them. So, I humored you on a couple. |
WOW you are scary as a trans mech 1 answer 50% correct
wonder how you customers would feel about that
Auto tech test
1 what is the first measurement you should take when rebuilding a auto trans ?
the input shaft endplay , some may say the TQCon bushing ,but most feel that.... you should have answered this it plays a big part in diag too on tear down and install
2 what are the last two biggest innovations in design in auto trans?
really don't know this ! study ,you do not know much
they were from the 80's but were game changers
3 why did the manufacturers only recommend using their ATF in the mid 90s on ? the torque converter dampning clutch ,can wear early with out the exact friction modifier additive
4 What do the metal lines from the trans to the radiator go to/do ?
it is not a cooler, its a _______/ cooler ...if it was 15 below zero what would the trans need the heat exchanger is in the aft part of the rad , what temp is that
5 what is a good/easy way to determine if the trans pump is working sufficiently ? 1 easy way ,you do it every day
6 if a auto trans ,after sitting for a couple of days ,up one start up, has no pull ,then after running a min, or two seems to drive good , what part should be looked at for replacement ?
the torque converter bushing , will if worn excessively , the TQ con will drain down in the pan , must have never worked on mopar/jeep
7 On a carb, what is (after 1973 ) the correct way to adjust the idle mixture screws setting ?
my trick question ...anybody
8 what replaced the speedo gear drives on many auto trans , and how does it work?
9 what is the best way to be very accurate when doing a compression test , under what conditions ?
10 what is the name of the system standard after 06 ( on every car, cycle, watercraft etc.,) that prevents theft and what can it do ?
Immobilizer system its a $6 chip in every ECU/pcm
11 if you have a engine to lean trouble code ( I don’t know # it off hand ) what is likely or the first thing to check ?
you missed it unless you meant vacuum leak in the exhaust ...yes there is vacuum in the exhaust , I just blew many minds here. it pulls in air outside and causes the o2 to read lean
12 describe the EVAP system workings... in your words no answer ?
13 what was the parts update in early 2000s ...what can you do and cant ?
ask a dealer parts guy imports Nissan ,Subaru, Mitsu Toyota , had it ford too
manuf. were tired off salvage parts being put into newer cars so the numbers changed with very slight differences that gave headaches to the installer .020 here and such may go in but caused problems , noise etc.
14 whats the difference between the AWD and 4wd components
center diff with a viscous coupling
seems like these relatively easy know questions ( I knew them by heart) are over your head
