Question about 1996 GMC Suburban

2 Answers

No overdrive or 3rd gear

I recently heard clunking coming from the rear-end of my 96 suburban. The rear-end finally let loose one day and pretty much exploded in the rear differential. I replaced the entire axle assembly to avoid having to rebuild the insides. After the job was complete Ii decided to take it for a test drive only to find that I have no Overdrive or 3rd gear. 1st and second work, though. I assume when the rear-end let loose it did damage to the transmission. Some mechanic friends of mine mentioned something about an overdrive module? on the tailend of the transmission, but I've never heard of such an animal. Is there some way to get my gears back without spending a boat load of money to rebuild the whole transmission?

88 volvo 240 dl won't shift into 4th


This is common to the AW70 transmission when the rear bushing has been left very worn for a period of time. The rear shaft wear heavily on the main transmission housing causing the pressure not to build enough to engage the overdrive gear.

I have a 96 Chevy suburban and I was driving through the mountains and the transmission kept down shifting or slipping gears help?


Was it loaded with weight? Could have been overdrive. Vehicle should sometimes be dropped onto 3rd and left there under hilly conditions. So as not to shift too much. Suggest checking trans fluid level , possible trans filter change, or add trans cooler to keep temp down in fluid when in hilly terrain. Good luck.

best advice is dont go 40mph in 5th gear... if you are going up a hill at 40mph in 5th gear i have no doubt that it is jerking, your putting too much stress on the engine. shift up to 4th or 3rd you will be fine. 5th gear is an overdrive gear. 55+mph

Transmission passing gear keep either getting stuck or it dont work because the motor keep idling up in first gear


this could be relative to many things, however you should check a few things before asessing the possibilities. When you put the truck in gear from park, Drive (overdrive) Should be the third notch you come to. so your in park, pull down clunk you're in reverse, clunk you're in neutral, clunk, now you are in drive. If you dont feel/ hear four notches/ clunks, you should be in overdrive. If you take off and it over revs 1st ( you shouldn't see more than 15 mph before it shifts on a stock transmission unless your flooring it and taking off fast) and then hard shifts to second gear, progresses to third gear normally, but wont progress into overdrive, it may be related to your vaccum advance, your shift linkage, or even possibly your timing. From the sounds of it, I would say vaccum advance is the likely cause, if it is otherwise in stock condition. If this is the case it could be as simple as reconnecting a vacum hose to the distributor. Should be to the left hand side of the cap, between the cap and intake manifold as you are looking at the firewall.
