Please help! I've got a 94 GMC Jimmy 4.3 Votec manual trans. 2wheel drive. a couple of minutes after starting it up. it will only idle if you give it gas it will sputter and die. i looked into the throttle body while given it some gas and the flow from the injectors stops when you accelerate. theres also a strong odor of gas fumes or exhaust. thanks, joe

I would get the repair manual and retrace your steps. otherwise you may have a defective torque converter.

I would use recommended filter pressure could be different and could possibly cause an issue not to mention filter media area coverage imo.

you have way too much fluid in trans !!!!!!!!!!!! remove trans pan, drain out fluid, replace gasket and filter, put in (4 quarts) fluid. MAYBE ! DONOT OVERFILL !!!!!!!!!!!!!!!!!!! DONOT DRIVE UNTIL YOU DO THIS !!! NOW, START ENGINE, LET IT WARM UP, CHECK FLUID LEVEL, IF ITS TOUCHING THE DIPSTICK TAKE VAN FOR A SHORT RIDE, AROUND THE NEIGHBORHOOD, (5-10) MINUTES, THEN , WHILE ON THE LEVEL, RECHECK FLUID LEVEL, 3 TIMES, WIPING OFF THE STICK EACH TIME, YOU WANT TO SEE THE FLUID LEVEL IN THE MIDDLE OF THE "HOT" CROSSHATCHED AREA OF DIPSTICK ! IF THATS WHERE IT IS, CONGRADULATE YOURSELF, YOU ACTUALLY DID IT RIGHT !!! LEAVE IT ALONE, GO ON YOUR WAY. NOW, IF YOU NEED TO ADD FLUID, USE YOUR FUNNEL, ADD ONLY A SHOT GLASS @ A TIME ! DO YOU HEAR ME ????? A SHOT GLASS @ A TIME, NO MORE, NO LESS. EVERYTIME YOU PULL DIP STICK OUT, WIPE IT OFF, WIPE IT OFF, WIPE IT OFF !!! MAKE SURE YOU RESEAT STICK ALL THE WAY IN ! REMEMBER, THE ENGINE MUST BE @ NORMAL RUNNING TEMPERATURE, WITH GEAR SHIFT IN PARK, ENGINE RUNNING !

Sounds like 2nd gear in the transmission is slipping. Cars usually shift at 15-20 mph from first to 2nd. First check the trans fluid.

I would not recommend flushing trans fluid you risk
getting debris into the solenoids

You will get people telling you other wise

I just remove the pan clean it & refill

If a trans is old it may slip if get all the fluid out
by flushing

You drive a couple weeks then if it is okey you
drop the pan & change it again & that time change
the filter

I did once own a trans repair shop, I'm giving you
my opinion on 48 years personal experience,not
as a former business owner.

You change trans & power steering every 3 years
& never go over 30,000 miles on any vehicle

Use the correct fluids & NO ADDITIVES

u may have a lock hub failing 2 engage on front axles.if u have autolockers they have been knowen 2 seize up.some times a strip down&clean out®rease will sort them out also check the front jack shalft from transfer box 2 front diff make sure not lose or play in unijoints

Try cleaning the EGR, there common to carbon build up on the 95 JImmy's.

there is something wrong with you 4wd system might be electrial problem get it check be gmc service tech for diag code

Usually when a truck gets stuck in 4 low you need to put it in reverse, start backing up very slowly, put it in neutral (or push in the clutch on manual trans models) and stop the truck with the brakes. this will release the load on the gearing which should allow you to shift out of 4 low.

If you press and hold the 1&4 or 2&3 buttons together for 6 - 9 seconds a 3 digit number appears (xxx). Hold the AM FM button a second 3 digit number appears (yyy)

Call 1800-537-5140 when recording starts press 106010*xxxyyy* and it will give you your code

My 97 jimmy wont give me my second 3 digit code but good luck
