How to tell which transmission is in my 1994 gmc 2500 van

On most vehicles the transmission information is inbeded the VIN # or vehicle identifation number . Unfortinatly on GMC and CHEVY its not . It is stamped on the passangers side of the transmission at the rear of the oil pan just above the pan gasket you will likely have to clean it off to read it it will be a 9 digit # with letters being in it . The most common transmission for an automatic is the 4L60-E If the forth digit is D thats what it is . As far as the leak goes you need to deturman where its leaking from the pan gasket or the rear oil seal or is it comeing from in front . Transmission do not normanly leak so make sure that its not engine oil you are seeing that is being blowen back witch is much more comon . Transmission fluid is red and smells differant then engine oil and is thinner . Check the oil level on the transmission see if its red and dose it smell burnt if so it will be more black witch is vary bad . Do you have any shifting problems .Also check your engine oil to compare the 2 oils . In a nut shell its your vehicle and your the olny one that actully look at it and looking saves money and blindly replaceing parts costs a lot and rearly fixes the problem

Had the spark plugs and plug wires changed on my 1994 GMC Safari minivan, and now it runs very rough. If I stop, the engine shuts off. Backfires a lot also. The whole van shakes bad going down the road....

If your Safari did not expecience these systoms prior to you changing the plugs and ignition wires, then you may have crossed two or more of these wires when they were repalced.

I want to remove the alternator on my 1986 GMC 2500 Van.

Disconnect and label the wiring harness connections to the alternator (Painters Masking tape works very well for labeling Automotive wiring).

Loosen the alternator pivot bolt.

Remove the bolt that attaches the alternator to the adjustment arm.

Rotate the alternator to loosen the drive belt and disengage the belt from the pulley. Be careful that any spacers that are used in mounting are kept with their original bolts. This will make correct reinstallation much easier.

While supporting the alternator remove the pivot bolt.
Remove the alternator from the vehicle.

To reinstall the alternator, reverse the removal procedure.
