#1 of 75 Chevy Suburban Transmission Problems by 70ss454_man Jan 25, 2007 (6:24 pm)
I own an '88 Suburban, and I have posted here before. Now, I have a transmission problem. Does a transmission that "whines" in the morning when it's cold mean that the transmission is failing? It also doesn't want to shift out of reverse and into drive, or out of first into second. Once the vehicle warms up, the whine fades away into only whining at the top of every gear, until it is completely warmed up. Once it's warm, the transmission shifts perfectly, and the whine completely ceases. It doesn't slip the slightest bit, but it does however, like to kick back into first when turning left, causing it to surge forward, and depending on how fast I'm accelerating, kick the rear end loose and I fishtail some. This all started about a week ago, when my area got the sudden cold weather. Replies to this message: rhtrans (Jan 20, 2008 8:31 pm)
#2 of 75 98 GMC Suburban 2500 7.4L 4x4 question by pbuono Feb 15, 2007 (10:56 pm)
I have the push button 4WD and when I engage the 4WD and drive it for 1-2 miles the service 4x4 light comes on but I still have 4WD. But I cannot disengage the 4WD until I turn off the truck for a few minutes then re-start it and it will then dis-engage. Anyone?    Thanks Replies to this message: geiringe (Feb 26, 2007 7:27 am) lrawson (May 21, 2007 9:01 am) yonose (Sep 22, 2007 12:07 pm) frey3581 (Jan 20, 2008 5:42 pm) okierod (Sep 23, 2008 9:29 am)
#3 of 75 2000 Suburban shifts hard between 3 and 4 by geiringe Feb 26, 2007 (7:27 am)
Replying to: pbuono (Feb 15, 2007 10:56 pm) My 2000 suburban tends to shift hard between 3rd and 4th gear when the transmission is warm. I can drive for 10-15 minutes with smooth shifts but as soon as the transmission warms up I get this problem especially between 3rd and 4th. It only happens after I have accelerated and releases the pedal. It immediately shifts hard. Almost always between 3rd and 4th gear, but on rare occasions (months apart) it can happen on lower gears as well.   I'm not sure what happens when the transmission warms up that could make this happen. Any ideas? It feels like the transmission misses a shift and on the next turn it locks into position really hard and abrubt.

#4 of 75 96 suburban transmission keeps coming out? by 96burb May 13, 2007 (5:23 pm)
My suburban has had 3 transmissions,the one it came out with, and one replaced under factory warrenty both of these with the first owner. The second transmission came out on me at 180,000 and my replacement came out at 240,000. Is this a defect with this model 4wd 1500 LT. What would be my best options for replacing the transmission? Can I put a 2500 series transmission in mine?

Replying to: geiringe (Feb 26, 2007 7:27 am) I am having similar problems with my 2000 / 2500 suburban. It started out with occasional hard shifts and now I get a shutter at low rpm shifts. I am wondering if you ever resolved your problem?

Replying to: 70ss454_man (Jan 25, 2007 6:24 pm) The first thing i would check is the fluid level. when its cold the fluid contracts making the level very low, this could be causing the filter to suck air which in turn causes the pump to airiate and make a whining noise. as the fluid heats up it expands bringing the level up allowing the filter to its job..sounds like when you turn a corner it may be falling out of gear due to low fluid level. The late 1-2 shift and won't come out of reverse...may mean a bigger problem, but i'd certainly check that first. Make sure when you check it it's warmed up good, its in park running and on level surface. If it is low, there must be a leak. add fluid...recheck, if ok repair leak and service the trans (filter & pan gasket)...not a flush
