1 Answer

I was wanting to buy a 1980 928 but on the test drive it lost all power @3700 rpm and the manual trans would not go into second gear as it would just grind...i am very mechanicaly inclined so could i fix these problems myself or would i have to spend thousands at a shop?

I would pass on the car my friend..the two things that you dont want wrong with a car when you buy it, the motor and the trans...this one has the possibility of having both problems...needs new trans for sure and the engine losing all power is just a gamble.. porsches are one of the most expensive cars there is to get fixed and they need fixing all the time even when theyre new

TRANSMISSION GOES INTO GEAR (REVERSE AND DRIVE) BUT WILL NOT MOVE. 2004 SUZUKI VERONA


auto trans.101
1: check levels by the book, not like engine. RTM
2: check fuses.
3: scan it, or get it scanned. for transmission errors.
if car wont move and RPM goes high as foot presses guess
that is trans slip.
of RPM (engine) does not rise or only tiny,
that is lost engine power, total loss. but idle. (can happen)

Jeep sluggish between 15-18 rpms during shifting from gear to gear. what is the problem


i cant get that slang, DIff , gears, clutch to jibe. 1990 wrangler YJ
what does DONE mean.?
front or rear diff axle new, new transmission? what?
1500 to 1800 rpm 15 is engine stalled, or rpm of oil tanker ship.

got a MANUAL stick or automatic slush pump gear box?
but is no way to answer. you.
its a hydromatic A/T. right>? AUTO?
if yes,it has.
no electronics then. so clean AFT/ levels per operators guide not guessing? hot?
stall test pass (ask)
line pressure tests pass
kick down cable not stuck
or if M/t do say so, mine is, 5 owned..

but we only have one word here, sluggish to work with,
so that can be :
1: engine weak? (low rpms in all gears, and low power)
2: Trans slips (or flares) High rpm and low power (slip)

which is it?, the rpm in each gear answers that.
the FSM shows the range of rpm for each gear. ever seen a real FSM book? factory service manual.

lost engine power, or transmission slips????
which is it?
the engine rpm tells you if the engine is weak or transmission slips.
2.0 liter , DOHC I4, J20 engine.
which transmission, my guess A/T box. (sounds like?) sure..
test one
1: in drive. pointed in safe direction, say a field or ?
2: parked, hand brake and foot brake held hard and fast.
3: race engine to wide open throttle for 1 to 3 seconds.
and lift right foot. after noting RPM. quckly.
4: rpm below 2200 rpm is a weak engine , if the engine spools
wildly up to 3500 rpm or more, the transmission is bad. (slips)
this is called the stall test. (in the FSM)
2,300 - 2,600 r/min. for H25/J20 engine
stall test passes. so does the transmission reach 4th gear.
1,2,3,4? yes/ .no.
yes, the its not the transmission.
if engine power lacks in any gear, that is the engine. weak.

this post is about the engine power, (my answer)
will you change 100 more parts guessing?
why do that?, any shop can diagnose it for a fraction of your guessing.

if the trans dont slip
  1. over heating? the engine?
  2. never done a tuneup this decade?> really?
  3. low fuel pressure?
  4. low engine compression.?
  5. Bad MAF sensors or just dirty?
  6. check engine light on running?, why ignore that, scan it.
  7. weak spark , see #2 and 6
  8. leaking or clogged injectors. or stuck on, for 2 reasons.
  9. Intake vacuum air leaks>?


both the engine and transmissions are complex
as is the vast number of tests to do. based on previous tests and logic.
do you want to test or gue$$?

I was driving my 1996 Subaru Sportswagon manual 100km/h in 4th gear, bringing the rpm to about 5,500 or so. It was a mere test, comparing the diff of the Sportswagon and a Datsun I drove earlier that day....


If you lost power steering and all those lights came on, then what you experienced was the engine stalling.
If the car runs well aside from this single incident, then I wouldn't suggest that anything is necessarily wrong. You may have accidentally stalled it perhaps?

Why dosent my car advance when i step on the gas pedal


From what you say Daniel, your kickdown cable need's to be adjusted, here's how :

Down at the pressure lever on the front of the trans, loosen off the cable retaining nuts so there is a little slack in the cable.
then start taking the slack out of the cable a little bit at a time;
Rest a long screwdriver on the end of the pressure lever, holding the screwdriver with one hand start opening the throttle with your other hand.

Just at the point the idle RPM barely rises, the pressure lever should just barely move.

Driving test; Going along a level road at 25 mph light throttle, floor the gas pedal.
The trans should downshift to first gear.

repeat the same drive at 28 mph, floor the gas pedal, the trans only downshifts to second gear.

My check engine light came on and i pulled the code po732. what does it mean?i have a 2007 chrysler pacifica awd. I'm lost can't find a manual


Most part places will have manual's.

Code - P0732 - Gear 2 incorrect ratio.
Transmission problem. Could be a sensor, I would reset computer see if it come's back, if it does have it check out could cause major damage if not taken care of.

Spradic problem


Try to have the mechanic look for "downshift kickdown" service info. When you are driving and the cars computer senses a load that is beyond the limit of the present gear, the car will downshift into a lower gear to match the load.
The inbetween gear time is when the RPM rises because the gears want to change and the transmission has not caught up with the engine.
Some of this can be adjusted with the hydraulic pressure in the transmission. The torque converter supplies the pressure and the rebuilt trans needs to be matched with the torque converter.
Go back to the trans shop.

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.
