94 caprice good reverse but drive gears ar slugish
Hello Lionel,Couldn't sleep with this **** sinus infection making me hack - so here I am at 3:09 am playing fixya!! lolThis is sounding like the classic symptoms of bad shifting solenoid(s) to me... with that -- it sounds a lot more scarier then it is.First, be sure to inspect the power wires running into the transmissionand back to the harness, etc.,. to ensure it's not something real simple, like a broken wire or otherwise a bad electrical connection at the plug which transfers the power into the ******...If that's all good & clean with good contacts made, drain oil, drop transmission pan & remove the shifting assembly at the bottom of the transmission.*tip = Make sure you keep track of which bolts go where as they may be of different length. there may be around 10-12 or so (typically 10 mm or 3/8"bolts).tip* cover the ground area with cardboard or newspapers, there can be residual dripping...tip* when you are removing the bolts, keep the end ones at perimter in so you can drop the shifting assembly evenly as there are ball check valves up in there which may want to fall out!once out, move to a bench location to remove the solenoids - these little buggers either work or do not when powered. Herre, you may be able to re-use the gasket if extremely careful, these have a tendency to become brittle with age. (mine actually cracked and I still managed to cobb & reuse it, so I didn''t have to order a new one).I found a new (used) set by stopping by at a local AAMCO transmission shop -- where they were laying around in the closet!! - could not obtain mine for a 92 ford ranger at the ford dealer because of the older year model... My alternate was the Ford obsolete parts line -- which I got from calling Ford Manufacturing directly and talking sweet to the woman who answered... (grin) You may want to call your dealer ahead to ensure access to the part or otherwise may have to wait, unless you get creative like I did or otherwise have to otherwise order them. You might find them in a junk yard. Here, (again?) they either work or do not when you put dc voltage to them.With the shifting assembly at the bench, clean that puppy up a little if needed and make note of the ball valves. You may have to remove some spring clips or other holding the solenoids in, otherwise, they may be bolted in.Remove, replace in reverse order, try to use the same bolt pattern to be sure you do not mix any up, I don't think it will kill it, but is a good practice.As always, it may be a good idea to grab a haynes or chiltons repair manual to have on hand. They will have more specific detail for your year make model in the Remove/ replace, and testing etc.,. You can find a copy at your local library to check out for free (or order in from another library location) -- Alternatively, you could grab one for around $20 -$25 bucks at your local auto parts supply house -- Either way, call ahead to check on availability. These books are very handy to have around!You might also find more information below in "related questions."Let me know how you make out and good luck with the project and thanks for using fixya! And as always, please provide feedback!Best regardsCk
